where should i set my FP, throw me a number,

[OrangeMustangGt]

ive been messing around with my car alot, fuel pressure wise. I really would like to know, anyone with similar mods, with stock injectors, maf, etc what they/you are running for fuel pressure? my stock was 31 i believe. i have an aftermarket fuel pump, so i can turn it up if i want, just when i go over 40 it seems to stall at lights, but i never let the computer adjust so, i dunno, with what i have for mods, what do you guys think i should set my fuel pressure at? Also i have some explorer injectors which are suposed to flow like 1-2 lbs more than stock, plus they have less miles, but when i had em in my car with the stock fpr it seemed to run ****ty, what do you think if i put those in, and messedwith my fp?

I would think you would want to run your FP around ~45psi with the vac line off.

Not for running it, just adjusting it...vac off simulates your WOT pressure...

You are I are close mod wise....mines been dyno'd on two different occasions with different intakes, and 38 is the sweet spot with 14 deg. I run the stock 19s...
