i have a 05 with the following mods...perrin cai,agp wga,stage 1,forge bov,needswing dp. How many psi should i be at im spiking at 18 holding like 15-16 is this where i should be at or should i lower it?
lower it. 18psi starts pulling timing on S0/S1 cars so you're losing power that way. Spike 17 hold 15/16 and you may actually notice the car run even better
I have a Perrin FMIC, AGP WGA, 3inch down pipe and exhuast and im running the same thing with no problems....as long as after u get that 18 psi spike it drops back off to around 15-16 your fine
