Yeh i can speak from experience, The ZO6 is awsome!! I drove a buddy of mine's with intake, exhaust and chip. The low end torque is a big differance from a turbo fed Z. The last time we raced we boath got pulled over by a pissed off cop. We were going about 140mph and didnt see him behind us. But I got us boat out of a ticket with a fire chief's bag and a police detectives card. Oyher wise we would have boath been screwed!! Oh and if you want a good race with your friend start in second and break boost at the RPM you need for power and it should be a pretty good race:)
