    I have the screw out all the way on my JR FPR and I can only get my idle down to 58 psi. The 3rd green LED is illuminated on my autometer a/f gauge at WOT. I'll be getting a cartech soon since my JR FPR is very erratic. I've seen my idle pressure fluctuate anywhere between 35 psi up to 65 psi.

    I drilled the recommended hole in my stock pressure regulator and now it idles at a little less than 30 psi, unless I turn the JR regulator up too high.

    PSICYCLE: Did you just bore out the outlet on the OE FPR? Let us know if the B&M works out.

    Did you set your fuel pressure at 60psi at idle with the vacuum hose removed from our regulator as discussed?

    I emailed endyn staff and they sent me a drawing showing how to drill a hole in the regulator. It worked like a charm.
    I'm using a bosche pump and 370 rce injectors. I hope to have a B&M adjuster on the car by Sunday so I can lower the pressure even more.

    You drill a 30 thousands hole from the part that fits on the adapter into the part that the fuel exits from. It takes about two seconds to do when you take the regulator loose.
