even a minor slight breeze kicks it back onto the normal Transmission gears

even a few mods would help keep it in Super OD at 45 mph

Super OD only works at 40 to 45mph from my testing (but it seems everything is based on engine load and throttle...)

i would be able to get 30 to 35mpg most of the speed limits in my area are 40-50 mph so it would work great for me..

we would at lest need to shave it off from 0.34 to 0.32
