hey guys I wasn't sure where to post this so I just posted it in the noobie section.
i got a P0401 code today which says
"Exhaust Gas Recirculation Flow Insufficient Detected"
umm...I have a turbo back exhaust with a test pipe. i also got 750cc injectors. as far as fuel goes thats all i have done that I can think of. the map im running it is only pushing 13psi so its barely pushing the engine. Any ideas will help thanks guys.
