yall suck.... id like to mention that the fore mentioned car has a stock throttle body and fuel rail... there are several things limiting it other than the turbo. not to mention if u look at the boost graph ull see its like 20, not 16-17 psi. so is gaining 60 or so horse from 5 lbs really that bad? do you think maybe the stock t/b couldnt pass any more volume? are you so sure the turbo is not operating efficiently? can you spell efficient correctly? hell....did you think at all. maybe execelon didnt post all his info because the car is a work in process.... things change all the time. and all successful racers have something they hold back.... if you want a fast car do your own research, or pay a shop. dont leach off everyone else.
