what fuel pressure should i be running

[civicb18b]

as title says. here is my setup

94 LS motor
JRSC with crv crank pulley and endyn stepper
venom injectors
JR high flow fuel pump
aem fuel pressure regulator
JR FMU
kamikaze header
test pipe. 2.5 inch mid pipe
stock rear section

i'm at 60 psi with the vacuum off and 50 with the line on.

should i be running more or less?

Hmmm... how much boost are you making? The endyn stepper on the B18B1 AND the CRV pulley should be making 10 psi, no???

My car is at 9psi, with stock injectors... I assume you have 270's. Your pressure should be down towards 35psi. I bet you're running really rich.

8X5=40PSI over idle (peak FP 75PSI @ 8lbs)on 270cc.

We need more info... real boost, injector size...

In my experience, the B181, in a mellow state of tune, doesn't require larger injectors. I'm around 200 HP w/ stockers. This would greatly simplify your tuning.

sorry for not clarifying. yes, i have 270's.

with the endyn stepper pulley and crv crank pulley i'm pulling 9.5 lbs even though my boost gauge reads 11. i had a separate vacuum line hooked up the manifold and i could only produce 9.5 lbs. so i guess the autometer gauge sucks.

at stock fuel pressure i was leaning out. i know this because of the discoloration on my spark plugs and that is why i bumped up my fuel pressure.

so... i can assume 50 psi with the vacuum line in is good.
