I installed an Autometer A/F gauge, AEM FPR, and Apexi Vafc today. Everything went smooth except now im running lean as hell. On WOT im all the way into the red according to the A/F gauge and at idle it slowly moves back and forth.......i mean really slow. While on other cars with the A/F it moves back and forth with some speed to it. Anyways whats the best route to bring me back to stoic? The FPR w/no PSI gauge or the Vafc? I am open to all suggestions. I know the A/F is not 100% accurate.....but i want to be atleast in the middle of the A/F gauge.

Here's a list of my mods:
Greddy PE catback
AEM CAI
GSR head on B18C5 Block(pistons,crank,rods)
Mugen Headgasket
AEM FPR(no gauge to monitor PSI)
Apex VAFC
JDM 4-1

try getting a fuel pressure guage and set the fuel pressure to the proper setting. it can be to low which will cause you to run to lean.......

 

im thinking the same thing. Do you know if Pep Boys or another auto parts store would carry an item like the B&M?
