i have a b18b1 and i'm running too rich cause my car will bog and hesitate at higher rpms. i put a walbro 255 hp fuel pump when this started happening. so it raised my fuel pressure right? i got a fpr and adjusted it back down and i'm still running rich. i have a jrsc on the car also.

so now i need to mess with the fmu to get the fuel right, correct? which way do i turn the screw to lower the pressure?my fuel pressure is at 40psi. so when i rev the motor and it sees boost, how high should the fuel pressure guage go up to? my goes past 100psi, which i'm thinking is too high, right? i'm running 6psi right now.

any suggestions on what else i may need to do? it feels like i'm redlining when i hit 5k rpm. i also have my spark plugs gapped at .34, should i gap them at .30?
