Dropping fuel pressure FAST!!!
Dropping fuel pressure FAST!!! My buddie has a 02 Camaro SS with AFR heads and a cam..he just put a Fast 102 intake and throttle body on it with 42lb injectors and a direct port nitrous system. ON MOTOR right now when he floors it the fuel pressure goes from 60lbs to 20lbs in a sec and stays there under acceleration. So he bought a walbro 255 pump and still the pressure drops the same...WHY????? During this time the car goes way lean. What would cause all of this? Please help!!!!
