Just a little quick background of the car. 2000 GT, manual, Vortech V1 S-trim, 3.33" pulley, diy fmic, blow thru maf, bov, long tubes, o/r x-pipe. Had the car dyno'd with the supercharger a few weeks back and it made 330rwhp/341rwtq. Numbers seemed kinda low to me, but hearing from some other people the V1's aren't as efficient and the big ass intercooler is losing a good amount of boost. Oh yeah, I'm only hitting 5lbs.
Question is, how many more lbs. and pwoer do you think I can pick up with the AFM powerpipe? Should I just go with that and get it retuned or should I do the powerpipe with a 3.12" pulley?
Any help is appareciated. By the way, the car runs strong and smooth and very happy with the tuners work. Just would like more power.
