hey i have a question .. i have a 1990 GSx and i have a 16 g turbo and was wondering how much boost is to much. when i drive it it sometimes bucks and i think its fuel cut but i have the fuel pump upgrade so i think i have enough fuel but i still have all stock internals right now the max boost i run is 15 psi... i tried 18 but the car seems to buck a lot more when i do that. so if anyone could help me that would be appreciated..
