Help guys i trying to figure out why my car is running lean after about 5 mins of running. This is what I got on my 92 Civic HB:

greddy turbo
VAFC
AVCR
RC 450cc
AEM fuel rail
AEM pressure reg.
MSD 6al
p28 ecu
and all your other basic parts.

however, this is what happens. I would start the car, my AF meter would show rich. After boost @ 5psi for about 5 mins or so. The meter would stay around the red zone. Timing is good. however car idle a little rough. thanks for the replys

 

this is just a guess as i am hungover severly but wouldn't you want to get bigger fuel injectors, my bud with a 92 civ turbo (T3) Drag kit has like 750cc injectors or bigger just a thought

 

not at 5 psi but seems like u need to tune the afc to me
