well karlos my t34 starts spooling around 3200 and kicks hard at 3700 and full boost around 4100 i would of thought but when revved out you don't really notice the lag then but depends on the power your after, if it was me doing it over again i'd get a stage 2 as you were and get a 50 shot of nitrous in the mix then you could reduce your spool up time with the gas and then still have more power top end if you needed it would make one hell of a road car that would give most stuff a run for there money and be quick up the quarter like gav sty
