eckoxl hey everyone, I'm a newb!
alright. so i installed my AFPR and i cant seem to narrow down the pressure. i have GTP injectors. which are 36lbs, correct? according to grand prix forums, pressure should be at about 45 psi at idle, key-on should be about 60 psi, and WOT should be about 70 psi. my pressure gauge read 45 psi while idiling, but at key on, i cant seem to get it to 60 and the car dies/runs like crap. do i need to adjust anything with DHP?
