I finally made it to the strip with my stock 07 GT 5 spd (Flowmaster muflers only mod). First run went well but had some wheel hop. Second run I launched hard (with TCS turned off) and had some NASTY wheel hop, heard a pop from somewhere in the rear of the car. Immediatly the ABS & TCS warning lights came on and would not go off. In addition the TCS would not turn off after this. I turned the car off let set for half an hour or so and turned it back on only to find the same problem. When I left the track, I made it a mile or so down the road and the warning lights went off and the TCS was working properly again. Any help would be greatly appreciated!!

 

Did you try doing a search for this? I am pretty sure I remember another forum member had the exact same problem 2-3 months ago with wheelhop and the t/c turning on and loud popping.
