Complete SCT X4 Tuner and Custom Tune Package

SCT X4 in an F150 5-Star's 2015 F150 EcoBoost Custom Tuning Improves Power Output!
5-Star's custom tuning provides your 2011 to 2014 F150's 3.5L EcoBoost V6 with some of the best bang-for-your-buck power gains on the market in a simple, hassle-free package that can have your awesome F150 truck churning out massive levels of power with improved shifting so that your F150 feels absolutely amazing to drive. Your truck's two turbochargers churn out around 14 to 16 psi of boost pressure from the factory. 5-Star turns up your turbos so that they're spitting out up 18 to 20 psi of boost while adjusting your engine's fuel curves and ignition timing to take full advantage of all the extra air. The end result is a bunch more horsepower and torque that pairs with revised transmission tuning so that your truck drives beautifully and quickly in whatever application you have in mind. You get your choice of up to five 5-Star Custom Tunes in your choice of style and fuel octane, as well as SCT's canned performance tunes on your X4 device.
SCT X4 Tuner with 5-Star Custom Tunes
The SCT X4 is one of the most ergonomic, advanced, and easy to use custom tuning devices on the market today, and allows you to easily and quickly upload the 5-Star custom tune of your choice straight to your truck's Powertain Control Module. The X4 has a large, full-color screen and easy to use control buttons that allow you to quickly cycle through its menus and options to find whatever you need. The tuner can even serve as a handy garage tool thanks to its ability to read and clear engine codes and datalog engine running information to hep you pinpoint problems before they become disasters. The X4 comes with both an OBD-II cable for the device and a USB cable for your home PC for downloading new tunes and firmware updates from the internet. You can also purchase SCT's handy X4 windshield mount to help transform your X4 into an effective vehicle monitoring device.

SCT X4 PID Monitoring
The SCT X4 handheld tuner takes everything that was great about the older X-Cal 3s and SF3s and puts it all in a faster, better, and easier to use interface that makes tuning, logging, and monitoring your vehicle's performance easier than ever. The X4 features a huge, clear full-color LCD screen. Despite the huge screen, the device itself is actually smaller, lighter, and more compact than SCT's older tuners and comes with a removable cord for much easier storage. The X4 features an all-new interface with advanced firmware that makes all of the device's functions much faster than the older tuners and even allow the screen to rotate with tuner's orientation, much like modern smart phones. The buttons on the X4 are larger and more responsive allowing for quick, easy navigation of the X4's menus and submenus. The tuner comes with an OBD-II cable for hooking into your vehicle and features built-in WiFi that allows you to wirelessly download new tunes and updates from a computer on you network. If you don't have a WiFi network, the X4 also comes with a standard USB cable for hooking to your home computer. The X4 doesn't just tune your EcoBoost F150, it can also read and clear DTC codes, datalog engine running information, and display a wide variety of gauges on its large screen which makes it an effective vehicle monitor. SCT X4 Features
5-Star Tuned F150 on the Dyno! 5-Star Custom Tuning Tune Options
5-Star's tunes can turn up your 2011 to 2014 F150 EcoBoost's boost pressure while adjusting its fuel curves, ignition timing, fan control, and a ton of other variables so that your aggressive F150 build makes huge amounts of horsepower and torque. 5-Star's custom tuning even takes into account your truck's tire size, drivetrain, and axle ratio so that you F150 operates perfectly with your choice of tune. 5-Star's custom tunes are available in several different flavors for 87, 89, 91, or 93 octane gasoline to give you a huge variation in options for your truck. 5-Star EcoBoost Custom Tune Options

2011-2014 F150 3.5L EcoBoost Dyno Results from 5-Star Tuning

5-Star Tuning EcoBoost Dyno Graph 5-Star Tuning EcoBoost Dyno Graph
5-Star's custom tunes offer a huge increase in both horsepower and torque all the way through your F150's rev range, giving you plenty more to feel. The huge power increase is coupled with heavily revised shift points and shift pressures to make your truck feel much more responsive with much more low-end grunt and pulling power. Even 5-Star's 87 octane tunes can provide a massive increase in torque, especially in the lower reaches of the RPM range, where the stock tune falls flat and can suffer from noticeable turbo lag. The huge difference in torque and horsepower at 2500 rpm gives your 2011 to 2014 EcoBoost much more pulling power for towing, hauling, or rocking around off-road. While there is a more drastic drop-off in horsepower in the upper RPM ranges than the stock tuning, you still end up with more peak horsepower than the factory tune, allowing you F150 to breeze through freeway traffic without breaking a sweat.

Warranty vs. Non-Warranty Tune Note: there is no difference in function, horsepower, or torque between Warrantied Custom Tunes and Non-Warrantied Custom Tunes. The only difference between the two, whatsoever, is that Warrantied Tunes will have less parameters (i.e. tire size, gear ratio, etc) open to end-user adjustment. Please call us directly at 1-877-578-2433 with any questions or concerns.

Stage 3's F150 Lifetime Tunes Program

Stage 3 Motorsport's Lifetime Tunes Program

We here at Stage 3 Motorsport don't want to leave your F150 build hanging or force you to buy new tunes over and over again when you stack on new performance parts, which is why we started our F150 Lifetime Tunes Program. Basically, you'll get free retunes for as long as you own your truck when you buy products that require retuning from Stage 3 Motorsports. So, if you get a 5-Star custom tune for your truck, you'll get a a free retune down the road if you purchase a set of downpipes, water-methanol system, or other tunable part from Stage 3 Motorsports.

How our F150 Custom Tuning Works

Stage 3's 5-Star Custom Tuning Step-by-Step:
1. You place your order for 5-Star's Custom Tunes.
2. Stage 3 sends you a "blank" tuner without custom tunes.
3. You hook the tuner into your truck and pull its ECU strategy code.
4. You fill out our online tune form with the information from your truck and its strategy code.
5. If your truck has Ford's latest strategy updates, we'll forward your information over to 5-Star and get your tunes created.
6. Once 5-Star creates your tunes, you will be emailed a link to download them from our Google Drive.
7. Download 5-Star's tunes to your PC and then load them to your tuning device using SCT's Device Updater Software.
8. Now you can successfully load your 5-Star Custom Tune of choice into your F150.

After you order this system, you are sent a "blank" tuner without any custom tunes. Please be aware that SCT's devices and software are only compatible with Microsoft Windows computers, and will not work with Mac OS X, Linux, or other operating systems. Once the tunes are successfully loaded onto the tuner, you can then start to load your tunes into your truck. If we find that your F150 is behind on its latest TSB strategy updates, we may require you to have your TSB updates performed at your dealership of choice. Read our TSB Update blog post. If you need more information or assistance, check out our F150 Custom Tuning Page.

Industry-Leading Powertrain Warranty Options

Stage 3's Optional Powertrain Warranty Options
Stage 3's Aftermarket Warranty Coverage Details Whenever you put an aftermarket ECU tune on your F150, there's a very real possibility that any repairs to your F150's Powertrain won't be covered under Ford's Powertrain Warranty, effectively causing it to be voided. We're now offering aftermarket warranties for your F150's Powertrain with a 2-year/24,000 mile, 5-year/60,000 mile, or a 6-year/100,000 mile Limited Warranty available for your truck. Either of these warranties will cover your truck's engine, transmission, drivetrain, front and rear gears, and any other hardware found to be damaged because of our custom tuning from 5-Star.

These warranties are much less expensive than nearly any other aftermarket warranty on the market and they give your truck up to $20,000 of coverage which even includes labor! The cost of our 5-year/60,000 mile warranty works out to .83 cents per mile, while our 6-year/100,000 warranty works out to a full penny per mile. That's inexpensive insurance in case anything happens to your aggressive, custom F150 build.

All you need to do is select one of our Limited Warranty options from the menu above. After we receive your payment, we'll email you our Limited Warranty Information Packet which has a registration form on its last page. Read through all the terms carefully then fill out the registration form, sign it, date it, and either mail it or scan and email back to us here at Stage 3. Once we've received and looked over your paperwork, your Limited Warranty of choice will be activated, and you can drive your truck with the knowledge that we here at Stage 3 have your back.

2012 Ford F150 4x4 XLT Supercab Ecoboost 3.55 axle
I bought this tuner as soon as it was available as a package through Stage 3 with custom tuning by 5 star. When I got the tuner I atrempted to load one of the canned SCT tunes in my truck, only to find the tuner needed to be updated using a windows based computer. I was slightly dismayed as I use apple products. Eventually I was able to use a friends computer, update my tuner and load my custom tunes on it. My truck is now an absolute animal! I've also noticed an increase in fuel economy when I'm not stomping on it. Im at about 18mpg around town. Up from 16. I'm thoroughly impressed with SCT's canned tunes as well as my custom tunes from 5 star. The tunes I chose were 93 performance, 91 towing, 91 economy, 87 performance and 87 economy. Mods to my truck so far are a derestricted stock air box with dry AEM filter and plugs gapped down to .028. Future mods include a 4" exhaust in the very near future which I will purchase through stage 3. Not only do they have the best prices around for late model Ford mods but their customer service is second to none. John hooked me up with my custom tunes quickly. I couldn't be happer with this tuner and with stage 3. Buy this tuner!

At first I wanted to be conservative and loaded the 87 performance/tow tune; I felt a difference, definitively, but I wanted more. Then I loaded the 91 performance tune, and let me tell you guys, this thing ROCKS; the truck feels like a sport sedan, so light and fast. With throttle at one third, it spins the tires when shifting from 1st to 2nd and from 2nd to 3rd; unbelievable! I also own an Audi A6 with the 4.2 V8, and let me tell you guys, my truck is just as fast! And I'm getting two more miles per gallon! I am really impressed! Great product, great customer service; they helped me updating my X4 tuner over the phone. Thank you guys!

13 F150 Platinum Ecoboost
PLUS- Good product for the price. Good features and settings. Canned and custom tunes perform as advertised. Actual 1-3 mpg gains on economy tunes and truck is very quick and responsive on performance tunes. Nice that x4 can correct for account for tire size changes and other parameters. MINUS- A big pain to set up on the computer/update software/transfer tunes, with no guide book, unhelpful website, non-existant customer service (via email and web chat). Tuning is not quick: takes 10-15 mins to tune. User has to sit there through entire process to push button to continue tuning. After tuning several settings on dash computer, radio, etc are nulled; so have to mess with whole stytem to get back settings after each tune. Comparing to Cobb tuner i used on another vehicle, this system is lacking. Keep in mind: After each reset the computer has to re-learn transmission shifting behavior, causing erratic shifting. Ensure serial number is verified in info email, custom tunes will not work if ID info has a typo.

I'm kicking myself for not getting this sooner. I went ahead and purchased prior to warranty expiration because I was confident based on other reviews and decided to test on my annual family camping trip. Hauling a small pop-up camper using the 87 ECO tune, I averaged almost 17MPG on the way there (vs. 12ish last year on the same trip). Since buying the truck, I haven't averaged 17MPG on any trip, let alone towing... well worth it!

Great Bang for the Buck!
I've been running the 87 perf/tow tune now for a little over 500 miles on 91 octane. Truck just keeps getting stronger and mpg's still creeping up. I was getting 14.5 stock with my level/wheels/tires. I'm now getting 16+. It was always my plan to run the 87 p/t on 91 just to play it safe mainly looking for better shifting. The shifting improvement is night/day over stock and power increase is the real deal. I'm afraid to install the 91 p/t as I may never want to go back. Thanks Stage 3/5*!

Giddy up!!!! Does exactly what is says it does. It feels like someone has kicked my truck in the ass every time I push the gas pedal. VERY happy with the performance I get out of my truck now. I did the 89 performance/tow and it is unbelievable. I can't even imagine what the 91 performance feels like. Do yourself a favor and get one of these now. It will pay for itself after a dozen or so fill ups (at least it will with my math and my 36 gal tank). It even allowed me to change the computer setting for my tire sensors so i don't get the orange light anymore.

2013, Ford F150 Ecoboost
Bought this tuner because I was looking for better economy on long trips when I am not pulling my boat and more performance when pulling my boat and messing around in town. When I received the turner I followed the directions and sent in the info to SCT. They responded quickly and said that my truck was 6 releases behind on updates. I called my local Ford dealer and they haven't dealt with anyone wanting to tune their truck so wasn't sure what the latest PCM strategy code is for my truck so they said to bring it in and we can hook it up and it will tell us what the latest is. I had to pay 1/2 hour of labor to get it updated. Sent in the updated strategy code and my custom tunes arrived in my email the next day. Followed the instructions and flashed my truck. Took around 15min I guess to flash and had no issues. It has been raining here since I flashed it and my truck seems to have more power and torque and interested in seeing how it goes in the next day or so when it is sunny and 60 degrees. Very happy with the purchase and look forward to trying the other tunes.

5 star custom tunes are outstanding. 93 octane tune is like driving a completely different truck. I can break the rear end loose with electric locker locked completely through 1st gear. I spiked boost pressure at 19.5psi on 93 octane. Trans shifting is right on with torque converter locking right after shift.

Worth every penny so far. Living in WV and rolling on 33's put a damper on the fuel mileage until i went with the SCT X4 with the custom 5 star tunes. I picked up 2.5 mpg with the 87 economy tune. On the 87 performance/tow i noticed very impressive gains and about a 1.5 mpg increase. I have not got to play with the 93 performance yet but I'm looking forward to it. In the flatter states i could see this increasing the mileage by 3-4 easily. I'm very happy with this purchase and the ease of install was excellent.

After receiving the device, I had to make a couple of trips back and forth between the truck and computer. I updated it using SCT's software before hooking it up to the truck, then after attaching the device to the truck for it to figure out what I was driving, came back in and updated the device again. Then I was able to pull my strategy code and send off to Stage3/Five Star. They turned around my tunes super fast, under 2 hours! The device itself seems like it can be a little finicky when left plugged in; I've had it lock up a couple of times. But simply unplugging, and plugging back in fixes this. The gauges are super handy to have available to monitor engine conditions. I only run 92 octane. I loaded the 91 tow tune. Immediate improvement in throttle response, and the truck came alive! More low end torque, the transmission seems to decide on a gear much faster and just go, instead of thinking about it forever. Also noticed that it is less prone to immediately downshifting on small throttle changes; it stays in a higher gear and lets the turbos spool up and do their thing. This means turning lower RPMs accelerating up hills and keeping the truck in its peak torque band, 2000-3000 RPM. Long trips I saw a 1.0-1.5 MPG improvement on this tune, over stock. I haven't towed anything yet but hauling several people and a bunch of gear, the truck definitely doesn't seem to care about the extra weight. Just loaded the 91 performance tune last week and it has even more pep. Fuel economy in town has dropped from the tow tune, but I'm guessing in part because it's more fun to use the pedal on the right. This thing screams! I can't believe this heavy truck can get moving so fast with no other performance modifications other than the tune. One thing of note on the performance tune - on warmer days, the engine fan kicks on high much more than in the stock or tow tunes. I asked Stage 3 about it and they said this is part of the tune, the cooling strategy is a little more aggressive as Five Star thinks if you're running the performance tune, you'll be in high boost all the time, and they want to try to keep the motor cooler in heavy traffic or idle situations. All in all I am extremely happy with the tunes and device, and Stage 3's service is great as usual.

This tuner is super easy to use and the custom tune process couldn't be any easier. I've already recommended this to three other people in about 4 weeks. They're all blown away by how much power the SCT tuner is able to get out of the Ecoboost. The week after installing the tunes I towed an 8,800 lb car and trailer about 2,000 miles round trip and the truck didn't struggle one bit. Never downshifted hard a single time. Even put it in cruise control for most of the trip. The guys as 5-Star tunes know the trucks inside and out. Absolutely worth the investment.

The canned tunes were noticeably better than stock but the 93 performance has been awesome. I've noticed a 2 mpg gain If you can keep your foot out of it. Faster turbo spools make this truck a blast to drive. Stop researching and buy already!

Customer Question Can you explain the 5 five different custom tunes so a person that doesn't know much about an automobile can understand the differences? They seem to overlap each other and choosing 5 out of 14 tunes is difficult.
Asked by:  - 10/18/2014
Customer AnswerStarting from lowest gains to biggest: "Trans Only" tunes don't add any power to your truck, but they do adjust the shifting, gear holding, and shift pressures of your transmission to help give your truck improved drivability. "Economy" tunes are designed to increase fuel economy by limiting the amount of time your truck uses its turbochargers and by adjusting shifter to be more economy-focused. "Performance/Tow" tunes jump up the power levels of your truck significantly while adjust shift patterns and pressures for firmer shifts and longer gear holding, which makes these tunes great for daily driving or towing. "Performance" tunes offer the most power, and have shift points and pressures that get your truck going in a hurry at the expense of some drivability.

Customer Question Will I have to reflash my truck back to factory settings each time I take it into the dealership for service?
Asked by:  - 7/2/2014
Customer AnswerIt's always a good idea. That way your tuner is unmarried if they decide to do a TSB reflash, and so they won't hassle you about modifying your truck.

Customer Question i am curious how a custom tune will void the warranty but a canned tune may not? if you can go back to stock settings regardless, whats the difference?
Asked by:  - 3/21/2014
Customer AnswerCustom tuning and "canned" can both result in Powertrain repairs not being covered under a warranty. Returning the truck to stock doesn't "erase" evidence that a tune was installed on vehicle, though there are some methods of hiding the fact that your truck was tuned at the dealership level.

Customer Question Are variables specific to my truck setup (provided in custom tuning info email) already included in each custom tune? I noticed the variables on the custom tunes read "stock". Does stock mean the info i submitted, or do I need to go back and update my changes for tire size (etc) each time i tune? I dont want to setup tune incorrectly or have errors.
Asked by:  - 4/8/2014
Customer Answer"Stock" would be whatever tire size you've already submitted for your initial tune, so you don't need to change it if your wheels and tires haven't changed. The only time you need to mess with that setting is if you've changed tire sizes since you ordered your tuning and submitted us your information.

Customer Question How do it get installed? And can it be taken out easily?
Asked by:  - 10/8/2014
Customer AnswerThe tuner uploads tunes through your truck's OBD-II port. Before the tuner uploads the tune, it saves a copy of your stock tune so you can return to stock later, if need be.

Customer Question What all do the Trans tunes entail ?
Asked by:  - 4/24/2014
Customer AnswerThe transmission only tuning alters your truck's shift points, converter lockup, shift pressure, and torque reduction management, which all works together to make shifting slightly firmer while improving the drivability of your truck for daily use.

Customer Question Truck is completely stock except leveling kit and air bags. I tow a 8000lb travel trailer and need a little extra for the mountains in CO. Would a custom tow tune still be as reliable as the stock tuning? Any other customers with similar needs/purchases giving any feedback? Thank you for your time.
Asked by:  - 5/5/2014
Customer AnswerWe haven't had reliability problems with any of 5-Star's tunes on trucks that are properly maintained and updated with the latest TSBs. From everything we heard, a dedicated towing tune is a huge help for extremely heavy loads. I would suggest that you give us a call directly at 1-877-578-2433 to order your tunes so that we can get them customized for high altitudes.

Customer Question With this programmer, are you able to calibrate the speedometer/odometer for different tire sizes? Thanks
Asked by:  - 12/3/2014
Customer AnswerYep. With non-warrantied tunes, all you need to do is know the revs per mile of your wheel/tire combination, the the speedometer and odometer will be adjusted automatically by the PCM.
