Advanced And Ergonomic SCT Tuner/Monitor with 3 Custom Tunes

Need more torque for towing your trailer? Dial it up at a moments notice with the SCT X4 Handheld Tuner and your new custom Towing Tune from 5 Star Tuning. With the SCT X4, you have the control of your 6.4L Super Duty's performance at your finger tips. This technologically advanced and ergonomic handheld tuner lets you change your Super Duty's performance for more horsepower, torque or better fuel economy when you need it. With 3 custom tunes tailored to your Super Duty's specific performance parts, we can dial in the perfect settings to get your truck running at peak performance. 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 operate quickly and even allows the screen to rotate with the tuner's orientation, much like modern smart phones. The buttons on the X4 are large and responsive, allowing for easy navigation of its menus and sub-menus.

Features 6 Total Tunes (including 3 5 Star Custom Tunes)

While the SCT X4 Handheld Tuner already comes pre-loaded with 3 "canned" tunes, our custom tunes are guaranteed to vastly improve your Super Duty's performance. Off-the-shelf pre-programmed devices are built to include the minimal changes needed to accomplish some additional power and mileage. They only change the programming that is common between all the specific engines they are intended for. We take all of the information you provide about any aftermarket upgrades you've made to your truck over stock (lift kit, over-sized tires, cold air intake, high-performance exhaust, upgraded throttle body, etc.) and create a specific tune to relay to your engine via the SCT X4 Tuner. Each of the tunes are built for a specific octane and application, giving you an enormous range of options to get your powerful 6.4L Super Duty running just the way you need it.

We can not provide custom tuning for DPF Deletes or tunes that disable the DPF. Please call us directly at 623-434-5277, if you need more information.

5 Star Super Duty 6.4L Custom Tuning Process

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 and part number, TCM strategy code and part number, and SWPN Number.
4. You fill out our online tune form with the information from your truck.
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 Super Duty.
9. If you have further questions, check out our Super Duty Custom Tuning Page or give us a call directly at 623-434-5277.

Tuning and your Powertrain Warranty: any aftermarket PCM/ECU tuning can absolutely result in Powertrain repairs not being covered under your manufacturer's warranty, making it effectively voided. Please take a look at Stage 3's Stance on Tuning and Warranties or call us directly at 623-434-5277.
