Rich 99 Camaro Minor Car Specs-
-Origianlly tuned by R.P.M. of NC- FLAWLESS TUNE
-Lq4 with l92 heads and Torquer V2 Cam
-Sux2bu Ram Air
-Ls3 Intake
-Long Tubes- 1 3/4
-AEM Wideband
-Stock ls3 injectors 39 lbs at 42 psi?
My problem-
I had sold my 99 camaro ss to a budy of mine and he ran into a nitrous backfire leading to a busted intake, busted MAF, hurt 1 injector, messed up the my 340 aeromotive intake, and busted my 98mm FTP lid.
How I fixed it-
-Installed a brand new 85mm MAF
-Sent my injector to Eric Der (all redone inside and out)
-Bought brand new Ford Racing Ev6 to Ev1 adapters
-Installed brand new 340 and brand new 99 camaro fuel filter
My new Problem-
-Fuel Pressure moved from 58 psi to 62psi so now it's pig rich, at idle and WOT
-Idle AFR- 12:1
-WOT AFR- 10:1
My Question-
-I have recently purchased credits for hptuners on my cousins laptop and i can get it within a simple 10 minute drive but my question is how are you guys "easily" leaning up these cars.
-I have tried VE table, PE for WOT now I'm at 11:4, tuned MAF, and Moved the open loop table to .91 and It still seems to be rich.
-Should I adjust IFR data to compensate for extra fuel psi?

I have the same problem running very rich at wot a/f instantly goes to 10
40lb injectors and 61 fuel pressure. My next move is to lower the fuel pressure
to 43 with the adjustable fpr
