I'm thinking swapping 3.55 gears in place of 3.73's should up MPG a bit. But I've yet to find any Mountaineer or Explorer with a 5.0 that has anything other than 3.73. If 3.55 was a 2WD only option, that'll make the swap a bit difficult for AWD.
I have equipment and software to program tire revs per mile, so if the system can't be programmed for different gears, a different tire circumference can be calculated to fake it. It can change the axle type / tone ring teeth but I don't recall if it has anything for gear ratio.
