ZO6 are fast but with the stock turbos maxed out (like his and mine) you will take them from a roll or from a stop (if you have the wheel hop situation taken care of) on stock turbos i'm running 20psi and i havent messed with the timing yet and i havent tried race gas just yet. i've taken out a couple of Z06s from a roll but thats old news, i'm on the look out for Vipers on this set up to see how it goes.
