It will take some tuning and you will need to add a wire from the PCM to the boost control. ZZ performance sells the wiring kit to do this. But the tuning will take a bit more work. You need software like HPtuners, or know someone near by that has it. Where are you located? As for your transmission. I don't remember if you have a 4t65e or a 4t65e-HD Same transmission, but the diff is different, as well as the right side axle.
