Anyone seen this OS in a 2005 gto? 12598977 I found that it's a os for a hsv clubsport. Not sure what the stock file should be any suggestions? Go back to a GTO os or use the clubsport. I'm having several issues trying to tune the car it was tuned with a different engine setup and now trying to reverse engineer the tune it. Any thoughts would be appreciated.
