Best IROC setup (I will not worry about the Nitro, Yuck). A bit suprised to get such low HP on this type of engine, what where the boys and girls at Chevy thinking. Thank you for making the best of what it has!!
My vote.

I use mathematics for a lot, trial and error, and testing , testing, testing. Start with the base tune and go from there. There's no magic bullet, just have a lot of patience.
