Stupid Pos

[Jacek]

ok this is seriously pissing me off.. im apoligizing ahead for the bad grammar and punctuation and whatever but i am to mad right now. the only way i can tune my car right now is with o2 voltage which my target goal is getting it to .92v and i dont really care right now to log the bastard. i richen my car to about .88v for 18-19psi of boost and the car hits fuel cut right at the at 17.5 psi. i tried to tune my car when the air temp was at 62 degrees on the thermometer and it was dark out. i have a feeling that maybe my injectors are too small but i remember when i changed fuel pumps that there is a blue check valve right before the entrance of the fuel tank. its missing and has a stupid inline filter there so i wonder if this might be part of the problem as well as too high of fp but whatever info anyone has, the better off i am.

tuning mods: RC 550cc injectors, walboro 255lph, s-afc, afpr.
air flowing mods: 19c turbo (600cfm) custom fmic i built, 2g maf, and a greddy type-s bov recirculated
with the maf screwed in all the way i have my afc settings at +25% and my maf is showing me hitting 1901hz of airflow. where it starts to act stupid. my crap shit afpr with the vacuum hose on is sitting at 35psi, and my 2g maf screw is turned in all the way, (way i found it in the junkyard.)

why is my car acting stupid like this? also since i have the spare blue check valve that goes above the fuel pump i see there is an arrow on it and was wondering which way the arrow is supposed to point.

thanks,
jacek

Larger injectors should help with the fuel cut if you can trick the ecu that its leaner with the safc.

+25%? If thats the case there's your problem.
