Complete SCT X4 Tuner and Custom Tune Package

5-Star's custom tuning provides your 2015-2016 F150's 3.5L EcoBoost V6 with some of the best bang-for-your-buck power gains on the market. This simple, hassle-free package can have your truck churning out massive levels of power and drastically improve its shifting. Your truck's two turbochargers make 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 loads 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, as well as SCT's canned performance tunes on your X4 device.

Select Tunes by Octane and Performance

5-Star's tunes can turn up your 2015-2016 F150 3.5L EcoBoost's boost pressure while adjusting its fuel curves, ignition timing, fan control, and a ton of other variables so that your F150 makes huge amounts of horsepower and torque. 5-Star's custom tuning even takes into account tire size, drivetrain, and axle ratio so that your truck operates perfectly with your choice of tune. 5-Star's custom tunes are available in several variations for 87, 89, 91, or 93 octane gasoline to give you a wide range of tuning options.

5-Star's Dyno Results for their 2015 EcoBoost Custom Tuning

5-Star's tuning adds a bucket-load of extra horsepower and torque to your 3.5L EcoBoost V6's output all throughout the rev range with both their Performance and Performance/Tow tunes, making your truck feel like a whole new animal. On 5-Star's dyno run with the stock tuning, their test truck managed to hit around 260 horsepower and nearly 350lb-ft of torque to the rear wheels. On their run with a 93 octane performance tune, their truck put down a whopping 315 horsepower and 445lb-ft of torque to the ground. Those are rear-wheel peak power gains of over 20%, all with greatly improved transmission function.

Even 5-Star's 87 octane Performance/Tow tunes make great power, putting down peak numbers of 305 horsepower and 375lb-ft of torque, which allows you to get a whole new feel for your truck, even if you only have low-quality fuel in your area or if 91 octane or higher-tier fuel is too expensive. What's even better is the low-end gains provided by 5-Star's tuning, which greatly improves your truck's towing and off-road performance. 5-Star's test truck saw gains of up to 100 lb-ft of torque at 2500rpm when using their 93 octane performance tune. The huge gain in low-end power is thanks to the tune's increased boost pressure which comes in much earlier in the rev range so that your 2015-2016 F150 EcoBoost sees a great gain in its pulling ability in lower gears.

Stage 3's 2015 F150 3.5L EcoBoost Dyno Runs with 5-Star Custom Tuning Stage 3's 2015 F150 3.5L EcoBoost Dyno Runs with 5-Star Custom Tuning

We here at Stage 3 made sure to grab 5-Star's Custom Tuning for our very own 2015 F150 3.5L EcoBoost Project truck as soon as we could so that we could make our F150 come alive with more power, more torque, and improved drivability. We did a comparison of our truck's stock tuning with 5-Star's 91 octane Performance/Tow tune on the dyno over at Dyno-Comp. On the dyno run of our factory tune, our truck made 300 peak horsepower and 360 peak torque. With 5-Star's 91 Octane Performance/Tow tune, our truck put down 310 horsepower and 415lb-ft of torque at the tires. The 55lb-ft gain in rear-wheel torque made our truck feel a whole heck of a lot more quick off the line, and when combined with 5-Star's revised shifting, made our 2015 F150 EcoBoost an absolute joy to drive. While we only gained about 10 peak horsepower due to heat soak on a 90, between 3000rpm and 4500rpm, we saw as much as 35 horsepower, meaning there's a huge improvement in low-end horsepower and torque over stock, which is exactly what you want in a Performance/Tow tune.

Stage 3 Warranty Options

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.

Off-Road Exhaust Systems: 5-Star can no longer provide custom tuning for off-road exhaust systems that delete catalytic converters. 5-Star can only tune for catted exhaust systems. However, 5-Star WILL NOT disable your rear oxygen sensors, which may result in a check engine light.
