Does the transmission have to be completely reprogrammed if you "tweak" the engine?
If I could have picked up 1.5 mpg on my last trip, I could have made a good down payment on the modifications. A little more shove would not be bad either. I used to be the fastest thing on a mountain with more than 8 wheels, until I got to AK. Those guys up there with the 650hp 18 speeds went by me like paint on a fence...pulling doubles!
