The 5.0L F150s are a little sluggish from factory, thanks to less than ideal mid-range torque and transmission shifting that's designed for fuel economy over responsiveness. 5 Star's tuning helps immensely by increasing low-end torque over stock, while adjusting your truck's shift points, pressures, and throttle sensitivity for much more responsive driving. More importantly, 5 Star's tuning provides increased power throughout the entire rev range so that you always have extra performance on tap. 5 Star's 5.0L test truck made 270 horsepower and around 285lb-ft of torque at the wheels. With 5 Star's 93 octane Performance/Tow tune, their test vehicle threw down 290 peak horsepower and 315lb-ft of peak torque, which makes for an instantly noticeable gain in power. Their truck even picked up gains of up to 25lb-ft of torque below 2750rpm, which is right where the 5.0L F150s are sorely lacking. Even 5 Star's 87 octane Performance/Tow tune was able to put down 275 peak horsepower and 295lb-ft of torque, meaning you can make your truck feel and drive much better than stock, even on low-octane fuel.
