    To get those rpm's you will prob want a 14/19 OR 15/20

    Hard to predict exactly as temps, altitude, etc etc change
    from location to location.
    You will need 1 of them to strart with, then take rpm and
    speed (gps) readings and tweak from there.
    14/19 is almost right for my mods in sig, but i'm
    only trying to get to 8300 rpms.
