| here's what i see wrong... intake with no exhaust. most of the time people do intake and exhaust the same time.... well at least that's what I and most of my friends did. It helpd the car breath. 850cc injectors with stock turbos @ 15psi. overkill on the injectors. 550's would have been more than enough. seriously, have your car looked at by someone who knows how to tune a Z. Dont go to just anyone. And get a damn exhaust!
