There must be some equation to back this up right?
Also, UPDATE:
my highway mpg is 15.6 (did some recalibration and remeasured)
This still seems crummy for a truck that has 283awhp, unless I'm just setting the bar too high
I'd like to swap rear end gears to something more appropriate, if in fact 15.6 is still crummy mpg for my setup. Anyone know of the calculation to choose the best gear so I don't have to do this twice?
Thanks for all the input guys! It's truly impressive how reliable this forum is
