    Certainly am, i upgraded from the stock x charger and i see around 11psi at 8000 (Hard to read off of the analogue gauge). I didnt have the boost gauge installed with the stock X-charger so i cant compare the numbers. I am not sure my boost gauge is reading right though, riva claims 13.5psi @8100. Anyways boost numbers aside, i really liked the improvement, the acceleration is pretty sick . I cant say for sure how many rpm i picked up either, i switched to the 15/22r and 83mm nozzle at the same time as the s/c upgrade and i saw the same rpms (~8060).
    Hope this helps

    Hmm I'm thinkin that gauge isn't working correctly or somethin is wrong.. Im seeing 12.6 with stock x charger buddy. If it's pullin hard then i'd say gauge.

    Yours sounds high for a stock X charger. I put a boost gauge on mainly so I could see when it might be time to adjust sc slip. If it shows 12, even if it is off, and then it starts to show less it would seem logical that the sc is starting to slip. BTY, I was seeing 12 psi with a Riva X charger upgrade turning 8300 before the head gasket went.

    Thats what I was thinking. 12.6 lbs seems a bit high... I was seeing 10.5 on a good day
