Complete SCT X4 Tuner and Custom Tune Package

5-Star's custom tuning provides your 2021-2023 F150's 5.0L V8 with some of the best bang-for-your-buck power gains on the market in a simple, hassle-free package that can have your F150 churning out massive levels of power with drastically improved shifting. 5-Star's custom tuning turns up the boost pressure output of your truck's two turbochargers 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 in whatever application you have in mind. 5-Star's tuning provides a drastic increase in low-end torque, making your 5.0L feel much more powerful in the low rev ranges than the factory tuning, helping you in both towing and off-road applications. 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 2021-2023 F150 5.0L V8'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. Regardless of your octane level or tune type, 5-Star's custom tuning adds big-time horsepower and torque gains to your 5.0L V8 F150, all while taking into account unique features and other performance parts on your aggressive F150 build.

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.
