Applications
The XRT Pro is capable of tuning the 6.7 Cummins engine and transmission SEPARATELY. This becomes handy for those running products other than H&S for their horsepower, but would like to tune the transmission with the H&S Overdrive software. For this application you will select "Transmission ONLY" on your XRT Pro the first time it is installed on a vehicle.
Or, if you would like to purchase an Overdrive unlock code the XRT Pro can tune the Engine AND Transmission on your 2007-2011 6.7L Cummins. You simply need to select your engine from the XRT Pro vehicle selection menu, and you will be given an option to unlock transmission tuning when you install the engine software onto your truck.
