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.
