    Installed Riva RRFPR, nice piece

    Finally installed the Riva RRFPR on my ski, setup is in my sig. Install was a breeze, no clamps, all factory fittings, went on super easy and secure. I needed a little more fuel, so initially it popped up right at 60 psi, and I adjusted it to 62 psi at key on ... interesting, my idle was a little richer, noticeably so, idle went just a little choppy. So fired up the AFR and went for a ride ... at 62 psi on the gauge, my AFR at WOT dropped from low 12s to low 11s! Seemed like a big switch to me for only potentially 4 additional lbs of fuel pressure ... so I adjusted it to 60 psi and rode, AFRs came up to about 11.6.

    This surprised me a bit, but may have to do a free air calibration on my sensor too next time I am out. Does that sound right that going from stock to 62 lbs static pressure would give close to a one full point drop in AFRs at WOT? I never bothered to hook up the reference line at all, does not seem I need it.

    I don't have my manual with me right now, but I thought stock fuel pressure was 58 psi ... might be wrong tho, maybe someone could check their manual if its handy?
