Does anyone have a supercharger and nitrous??????....if so what kind of combo is it and who tuned you....i have a forged dss engine with ported heads cams bullitt manifold and a d1 procharger oh yea it has stock compression...laroccas in nj tuned me and i only got 510hp and like 420 tq at about 14#s of boost i was very upset with the numbers since i made 390hp and 390tq with just a p1 and full exhaust at 10#s.... i know putting on a smaller pulley will add some hp but i was just wondering if you think its possible to get a small shot of nos or just go somewhere else for a tune...thanx
