Want MORE PERFORMANCE from your 1996 - 2012 GM Gas or Diesel vehicle?
We have a Wireless Smart Phone / Mobile Device for that!
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 / TSX for Android 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.
