i have the FMU so not sure about your setup but i would think your right, a vaccum leak could be one of the problems.

What's your base fuel pressure set at? Check to make sure the boost reference hose is not pinched or kinked.

hey dude, r u going to the meet on saturday? if i finish studing for finals early i might swing by to hang maybe i can take a looky..im from so cal near knotts email me if u really want me to stop by if i can

ahh these goofy HRC fuel systems :P

You can also try starting the car and taking it out for a 20-30 minute cruise run. Then get home and see if idle pressure is lower than it should be. I use to set mine at 50psi after 10minute warm up (let it idle) then after actually driving it would drop down to around 40psi. Just a thought.

well i have left the fuel pressure guage on my windshield for a couple days now and it wont go above or below 58 when idling and wont go at 85-87 psi fuel pressure at full boost. is it bad to run that lean?


o and im boostin bout 7.5 psi

do u have the stock hrc fpr? also at idle use the static screw to adjust idle 47-55psi i would say 50psi then lock it up... the brass knob is only to give or lessennn the fuel at your max boost nothing to do with idle... what is your max boost? 6psi? at 6psi it should be 85-90psi of fuel...
