Here is my problem. ---- I let superchips use my car for testing of new tuner being release. They wrote a custom program for my 2002 TA WS6. I installed the programming at the track and then returned it to stock. I then put their programming back in. A couple of days later i tried to return to stock and i have access denied. I could not get back into the PCM to change tuning. I took it back to superchips and they got it to work with their tuner by making some changes but they said something happened to the computer and GM would not be able to access the PCM. They are ordering a new computer for my car. ANYBODY have any knowledge as to what went wrong with my computer? They have no ideal what happened.

thanks
