Complete Bully Dog BDX Tuner and Custom Tune Package
5-Star's custom tuning provides your 2015-2020 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. 5-Star's custom tuning turns up your F150's boost pressures 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.
Select Tunes by Octane and Performance
5-Star's tunes can turn up your 2015-2020 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 tunes are available in several variations for 87, 89, 91, or 93 octane gasoline to give you a wide range of tuning options.
The 2017-2020 F150 3.5L EcoBoosts are already some quick trucks. Their torquey EcoBoost motors paired with a 10-speed transmission makes them blistering fast with the factory tuning, but 5-Star's custom tuning takes their excellent power and quickness to entirely new levels. 5-Star's test truck put down roughly 325 horsepower and 400lb-ft of torque on its factory tune. With 5-Star's 93 Octane Performance Tune, that same truck threw down 445 horsepower and 500lb-ft of torque at its peak. That's gains of 125 horsepower
and 100lb-ft of torque
. While the gains themselves are extremely impressive on their own, 5-Star's 93 Octane Performance Tune also features a more linear torque curve and carries its gains higher into the rev range than the factory tuning, which greatly improves drivability and feel. Even 5-Star's 87 Performance/Tow tune managed to hit nice numbers, picking up noticeable gains in torque while carrying more horsepower farther into the rev range.

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.
