    Around 12.5 -13.0 @ 8100. You'll need 48s or 50s & a rrfpr to run it on the stock ECU. I would recommend a BEGI 2025 also so it's not too rich at idle. I got a friend who runs one with a rrfpr and 50s. Dialed in the AFR with my LM-1. Can't remember what the base fuel pressure was set to, but I can ask if you need a good starting point.

    I would guess boost would be in the 12,s.
    In regards to fuel ,what you need is too borrow/lease a jpipe/bung and meter. I don't think anyone can honestly say you will be OK without knowing. Until you can get someone to tell you what there AFR readings where per that setup, then we are all just pissing in the wind.
    And even then you got boat and condition difference.
    Once you get an adjustable fuel reg you have to have readings to know which way to adjust it. Anything else is just best guess.
    I know its not the answer you were looking for but its the truth.

    I got a j pipe you could borrow if you could find a meter.

    Why not go with x charger without the ext ic??? Will lose some speed, but then you can just ride it temporary until you are willing to dish out the cash for rrfpr and the lc-1
