JR, I am considering a Z06 next year ('08 model)to race in a "stock" class in SCCA solo/autocross competition. I'm pretty sure tuning is not legal. My question to you is how easy is it for someone to spot a tune (other than kicking their butts) when looking at a flash assuming they know what they're looking at? I'm just toying with the idea, but I think your magic on a Z could really help me kill the competition. I also want to do some HPDE's with the car, so in a stock class in NASA I could annihilate some people...worse case they kick me out?
