If you purchase a spare TCM that's already unlocked from HPT, that TCM would still required to be programmed with your cars VIN number. So unfortunately you would need a GM TIS subscription in order to program your VIN to this new TCM, so yes that means you would have to pay a dealer to do it. That's where the world is heading with all these do gooders pushing driverless cars and other stuff its going to basically eliminate vehicle customization and tuning, turning them into basically iphones. This makes me want to get away from GM products, since I always though they were the least "locked down" apparently not though, but I believe every other manufacture is on board as well.
