This not only leaves valuable Horsepower & Torque hidden inside your vehicle, but it also makes for a mediocre driving experience. The SCT X4 Power Flash unlocks your vehicle's hidden performance by optimizing your vehicle's computer for Maximum Horsepower, Torque, Increased Throttle Response, Firmer Shifts & even Increased Fuel Mileage!
