    Don't know if this will do you any good. I have a stock port/compression triple pipe with Novi 48mm

    Altitude: around 950'

    Highs: 145
    Lows: 135
    2.3 Needle 95g spring

    2psi @ Idle
    4psi @ ~5k RPMs
    6psi @ WOT

    High Screws 1.5 Turns Out
    Low Screws .5 Turns Out

    Tuning was spot on, but with the higher temps lately I seem to also be having a bog off the line. If I ease into it, I'll be fine, but if I go WOT from idle, it will rev to around 4k, and then hang for a bit.

    Hope this helps...
