Ok, was able to write the factory tune back to my truck. I wrote the Diablo tune to the GTO and took it for a drive. Idle was nice. Whal driving, from idle to half throttle it would shudder, miss and had no balls, but from half to WOT its a good thing I had my seatbelt on couse I would have ended up ...

Im not sure. I bought it last year. I dont have a media kit for it yet. How do I see if it is 9rxx?
