This is the computer we've all been waiting for. GM has many modules. But the only module you couldn't hit before was the Air Ride. You had to take it to the dealer and pay for the code there. Contrary to popular belief, the air attraction is cool, easy to fix, and you'd be crazy to rebuild it. This computer is working like a champ when I received a terrible message on the dashboard. He pulled out the codes, it was the sensors, all replaced with an Arnott N/C that I used to upgrade my craft on my '05 Yuki Denali. There is also a mod for pumping the brakes. This is a great product at a great price.
