you have to buy the 1LE track pack to get it tuned. GM will not tune it if you dont. you dont have to install it for them to tune it. its not just the MRC tune its the springs. they lower the car 1/2" and are a little stiffer. the sway bars are a little stiffer then the SS. and the arms that come with it have bearings in them instead of bushings. the only thing you cant get is the Ediff and drive modes. i recommend just getting the 1LE.
