GREAT!! ThankZ 4 the info, I'll definitely dial those numbers in. Im thinking of trying to peak at 16lb. and hold 14. I have the Nismo thermostat so my engine temps are lower than normal... I think I can get away with that psi without detonation. Car runs nice and smooth now and havent had any detonation problems since. Now I just gotta find someone local who knows what the hell they'r doin to install or help me install this thing.
