I searched and found alot of mixed info as for FP settings. 3 bar = 44 & 4 bar = 59 i know this but i seen that some people are setting @ 36 which do I set it at? My set up: 370's, T25, DE maf, 4bar program, FPR, 255 walbro. Need just a little help clarifing Thanks.

Bar is atmospheric pressure at sea level its 14.7.... so if your computer is set to 6 bar multiply 14.7 by 6 and that's your number. Does that make sense?

yea i know that 1 bar = 14.7 thats not what i'm asking, with my setup im trying to figure out where to set my fuel pressure do i set it at 4 bars(58.8) or do i set it lower like what some people.

You've got it then set it to 4bar with the vac hose unplugged and capped and the car running.
