The 6.2L SVT Raptors may come packing some firepower from factory, but the factory tuning can still make the truck feel a bit sluggish at times, especially on the street in lower RPMs. 5-Star's custom tuning for the 6.2L Raptors helps change that by not only improving peak gains, but by providing increased torque all throughout the rev range, especially in the low end where the stock tuning tends to lug around until 3500rpm. The improved low-end power carries all the way through your Raptor's rev range, giving you more power on tap whenever you need it. 5-Star's test truck put down about a peak 280 horsepower and 300lb-ft of torque to the wheels on its factory tune. With a 5-Star's custom 93 octane Performance Tune, the truck hit a peak 295 horsepower and 320lb-ft of torque. While the peak gains of 15horsepower and 320lb-ft of torque are nice, the low end gains below 3500 rpm spiked up to a whopping 40 to 45lb-ft of torque over stock, which greatly improves the off-the-line performance of your Raptor. For those looking to add long tube headers to your truck, 5-Star's custom tuning has you covered and can add even further gains in both horsepower and torque all throughout the rev range of your truck.
