5 Star's Custom Tuning increases the horsepower and torque of your 5.0L V8 all throughout its rev range, creating a noticeable improvement in output whenever you step on the pedal. 5 Star's test truck put down 290 peak horsepower and 290lb-ft of peak torque using its factory tuning. With 5 Star's 93 octane Performance/Tow tune, their truck threw down 315 peak horsepower and nearly 325lb-ft of peak torque, an increase of 25 horsepower and 35lb-ft of torque. Even 5 Star's 87 octane Performance/Tow tune was able to provide a nice increase in power, bringing peak numbers up to 310 horsepower and 315lb-ft of torque, meaning that you can run less expensive fuel while still getting excellent power. The increased power output is paired with heavily revised shift points, shift pressures, and throttle adjustments to greatly improve the responsiveness and acceleration of your 5.0L F150.
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.
