a set of laser dv's would be a good investment and do you have your timing advanced. check out my vid, mine was a 98 12 valve 5speed. i was making 70lbs of boost and lanched at 4000rpm. i think if your able to run a 64 you wont have any problems winning the street class. they will tech it if you place in the money. i don't think you will do very good in the DHRA pulls they allow reducers , which allows guys to run large unstreetable turbos. i would concentrate on the EEP pulls and clean house, the payouts are just as good as DHRA and the rules are alot better. if you ever need any help let me know i sold my truck but i still have alot of the tools and know how. are you going to pull at london here in a couple of weeks it is a pretty good pull and lots of trucks
