    Assuming you have a reflash I ran static at 52lbs with my supporting mods. You really need an O2 to know AF is good. Pressure will differ depending on weather conditions and even from one motor to another.

    Yes you need a afr to really know. What are your mods and is your hull ventilated?

    Rising rate 42 psi at idle with hose hooked up, I'd say 64 on static with stock injectors YOU NEED A METER to read A/F

    You def need an o2.. When I ran the lb wheel rising rate didn't work for me and I had to run static. I'd say every ski is different.

    There is no point in a RRFPR WITHOUT A WAY TO MONITOR IT!!!!!!


    Its like playing with dynamite!!!! If you buy a regulator only install it if You have a way to adjust it properly, and not by someone else who has the same specs, no two motors with same parts are going to require the same fuel and air respectfully specially if there in to different climate zones!!!

    Get a AFR Gauge or you will end up like me, bending 4 valves and leaning the ski. Blowing your motor will not be fun.

    Depending on your ski and the climate you might need injectors. I have a buddy with your set up running an R3 and when the weather started getting cooler he maxed out his injectors. He had it like 55 lbs. rising rate hooked up. Could not get it below 12.5 He ended up getting pink STI injectors. He's turing 8600 rpm with 16-17 lbs of boost.
    First thing you need is the following:
