With that GM cars haven't used a removable eprom that you can change out for many years. So you would have to get a programmer that can reflash your ecm. The only one iam familiar with are the hypertech ones. That is the one I would get for my car.I used to be into all that when I was younger. But if my car takes me back and forth to work iam happy lol.
