Complete SCT X4 Tuner and Custom Tune Package

5-Star's custom tuning boosts the power and torque output of your 5.4L Triton V8 while adjusting your F150's shift points and shift pressures to get rid of hesitation and hold onto gears longer, using the added power more efficiently. 5-Star's F150 5.4L Custom Tuning offers up some of the best bang-for-your-buck performance gains on the market and can noticeably improve the drivability of your truck. 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.

Select Tunes by Octane and Performance

5-Star's tunes turn up your 2004 to 2010 F150 5.4L's power by adjusting its fuel curves, ignition timing, fan control, and a ton of other variables so that your truck 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 F150 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.

While 5-Star's 5.4L F150 V8 custom tuning does increase the power output of your truck, the tuning has also been carefully crafted to add power where it counts and make up for some of the weak areas of the stock engine management software. 5-Star's 2005 F150 5.4L test truck managed to put down a peak of 211 horsepower and 245lb-ft of torque with its factory tune. Using a 5-Star 87 octane Performance/Tow tune, that same F150 threw down an impressive peak 235 horsepower and 290lb-ft of torque, a gain of 24 horsepower and 45lb-ft of torque. More importantly, that 18% torque gain came in much earlier than stock and stayed throughout the middle RPM range, right where the 5.4L V8s tend to fall flat with the factory tune. Keep in mind, that the dyno graph above was with 87 octane fuel. With either 91 octane or 93 octane, your own truck can see even more impressive gains!

TSB Updates: 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.

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.
