Yup. Didn't get his last name, but his first name was Jeff. Ex GTO owner. Had quite a bit of grunt to it, but he kept having issues with the car turning on some sort of limp mode. If he pushed the engine to 7k+ RPM for too long, it'd almost shut itself off. I suggested keeping it under 6500 and that allowed him to do more laps, but it was still occurring. Seems a bit disappointing to have your new toy tell you how hard you can play with it. Any of the newer Zs have this issue?
