adding 31s how much power loss?
i got stock dana35 with prob 3.55 gears, jeepy came with a hitch but idk if i got the 3.73, im upgrading tires from 29s to 31 m/ts, and was wondering how much throttle response/mpg i would lose. also adding a tranny cooler

i lost about 6mpg right off the bat, and then did a few upgrades to get most of it back. right now i'm about 2-3mpg less than stock.
