Alright, since ive installed my exhaust the ECU has adjusted the timing 2 times since, and now in between shifts it sometimes will bog down then recover, im running insanely rich too, my car floods and i have to pump my pedal at times while starting and it puffs a cloud of smoke then smells of fuel pretty strong. Im thinking my ECU is taking a ****e....I cant get 2 consistant pulls with it driving, track or anything, its like it cant make up its mind, so im going to check it out tonight, reset it and see what she does...Today it thru a check engine light, i pulled over turned it off, checked it out, started it up, no light, wrapped it out to 7k 3-4 times nothing. I think im fouling o2 sensors, i killed a wideband with richness when i first got exhaust so i think im still wayyy too rich.....

Any ideas would be appreciated
