hey guys i recently found out that my fpr was bad so i replaced it and the car was running good was 13.5 a/f wide open bout a week later it is ding the same thing it was before it leans out to 14.1-14.5 during wide open , if i dsiconnect the fpr from the intake mani. vacuum souce it runs good i get 13.5 in first but only 14.1 in sec. gear, what could be causing this any ideas are helpfull also i replaced the fuel pump and fuel filter

 

what ems are you using and what wideband? might need some gear correction. shouldnt have to but if you have no other choice, add 3% in 2nd, 6% in 3rd, 9% in 4th etc..

 

got no kit on yet just stock ecu that is why i'm trying to figure out what is wrong first

 

can anyone help, trying to fix this problem so i can throw my turbo kit on
