i didn't actually have corey do any tuning at slomo just cause it was the dyno day. I did change boost a little between runs, but that was just to try to get the A/F to come back to where i want it. other than that it's just a standard VF30 map.
you can do better than 12.99. I did 12.94 at national trail (with a broken header running 14psi) and 12.85 at Richmond Dragway (as the teeth came off of 1st gear in my 5 speed).
