The SCT iTSX Wireless Flash Device 4416 increases power and performance in your 2006-2010 GM 6.6L Duramax. From the factory, your vehicle’s computer is calibrated for the masses, designed with the average driver in mind, not the performance enthusiast. This not only leaves valuable Horsepower & Torque hidden inside your vehicle, but it also makes for a mediocre driving experience. The iTSX System unlocks your vehicle’s hidden performance potential by wirelessly re-calibrating your vehicle’s computer for maximum horsepower & torque, increased throttle response, firmer shifts and even increased fuel mileage.
