working on a 06 gto that I have switched to SD with a 2 bar map OS. factory ls2 engine, summit pro ls stage 2 turbo cam, 80lb HP injectors, 7875 turbo, T56. I can drive the car all I want to as long as I do not go wot. I have to be missing something but not sure what. Only codes showing up are for MAF and A/C. I have attached the tune and the last log of me driving and it went into limp mode.
