i just put my vafc in my prelude and i need some help with what i should be doing to tune it.... i have an h22 with intake, full exhaust, adjustable fuel pressure regulator, and a walbro 255 lph fuel pump.... right now my fuel pressure is at about 48 psi at idle and i have slightly tuned my vafc and the engine light came on for an excessively rich reading from the O2..... i have no idea what fuel pressure i should be at with my few mods or how i could make my most power....any help or suggestions would be greatly appreciated
