Fuel pressure

[LeYepez]

so, at last im gonna use myy stage 4 re-cal with all the stuff needed (3 bar map & +40's)
im not going to use the car in a race o anything like that, im gonna use it as a daily car, so i would be using 18 psi of boost max.
my question is, how much psi i must use on my accufab AFPR??? (not using wideband)
Thanks everyone

No one except for the wideband can tell you if you're running rich or lean. Rich, you drop the fuel pressure. Lean, you raise it.

Get a good wideband.

yep, a good wideband is a must and with aem widebands at $200 or less, no reason not the run one. Once you get that installed, you can adjust FP according to the af readings....
