Thread: whats wrong with this thing???

first of all, adjust you FP, if your setting is for 4 bar then you should run it at 4 bar, if issue continues then try with another maf

i got her running now runs a little ruff when its cold if i hit the throttle when its cold it revs up and down a little but its just a littl e more fine tuning but i just ordered a nismo fpr its tuned for 57psi as i was told and im @ about 35 so ya that could be an issue

^^^^ what pump do you have because the that I know of the fuel pressure wont go any lower than 40 psi with a walboro. 35 psi i very odd

i dont know how accurate nmy guage is eather

And that is with the vacuum hose off???

my motor does that exact thing when my MAF is disconected .
