Nice #'s, and as predicted, stg 1 max out on 17 psi, any higher and the pcm will start to pull timing. But I'm glad to see the dyno results that would prove this theory. Thanks for the post, and like most peeps says, with your setup, it's not really that far from stg 2. You must have big time traction problem or wheel hop with first gear. I know I do.
