**** happens... You probably are running a little lean and not making much boost with all of your flow mods. There are a few cars that i scan the first time and are just dog slow, after a couple maf tunes and added timing, it wakes them up and your doing rolling 30mph burnouts and second gear scratches. I wouldn't take much from a 1/8 mile track anyway except for your 60fts. and the practice that you can get on those..
