Hey Guys! I have a '92 YJ with a slight problem. I have installed Borla headers, K&N FIPK, throttle body spacer, and taken the cat. off. My problem is my OBD is telling me I am running lean. It's a '92 so there is no O2 sensor after the collector pipes but I was wondering if I purchased an adjustable fuel pressure regulator or higher rate injectors, would this help with my lean problem? From what I gather, after all the "air upgrades" and not doing anything to the fuel delivery system I am starving my air-to-fuel ratio for more fuel that it cannot get with the stock setup. Let me know if this is correct. All the input available would help. Thanks.
