More A/F probs on 98 gst
As you guys know already I just put 550cc injectors, a walbro 255 fuel pump, new fuel filter, megan fuel pressure regulator and gauge, and an evo mr bov. Then i tried running my car on stock settings and it would jerk everytime I hit the gas full throttle..... only whenever the turbo spooled hard at about 4500 rpms. but if I ease onto the throttle it will go all the way to redline. I just bought a new afc neo. I need to know what you guys think about how much fuel pressure i need to run and i need some tips on tuning it with my new afc. Oh and everytime it hits the 4500 - 5000 rpms and jerks the fuel pressure drops harshly..... what do you guys think???

well if you plan on tuning with the AFC you need something to monitor it. Wether it be a wideband or an EGT guage. Wideband is definetly preffered. As far as the fuel pressure. What do you have it set at now, while at idle?
