Ive been running a jeep xj built 4.7 stroker for around 1 year now, Its been on Hp since October. Finally desired to correct the fuel trims by locking out closed loop, pulled the O2 and disabled. Reset pcm. Started her up and shes running at 12.80 idle, so I start pulling fuel out via EGR off map..... No mapped how much I pull out shes still sitting at 12.8, min injector pulse has also been lowered, seems she cant go under 5.0 ms no matter what i do, normally closed loop shes at 2.0-2.5ms tops. Am i missing a step here?
