Wow, it is kinda fun to read back through this thread!! The '11 GT was still pretty new and we didn't know the full capabilities of it yet. BTW, my uncle was so impressed with the performance of the '11 GT's that he sold his '03 Mach 1 and bought a new Performance White M6 '11 GT. He has already modded it with a midpipe, axleback JLT CAI and a 93 octane tune. I have since added a Procharger to my car.
