Dillz Three pedals are better then two..

I believe at least 2.5/2.75 is needed to help airspeed and drag for decent power...pretty much gotta change everything no stock look, new front pipe for boost sensor etc etc. Dont see the pointMissed this one, It's the stock hot side pipe to the cooler that is the main culprit for huge restrictions in the standard system. As crap as the crossover and pipes from the turbo up look they will flow the boost you need.From memory I think a 10 second pass has been done with stock crossover just to illustrate that fact.But ideally the better the flow the less boost you need to make power, which is safer for your engine.
