since it hasn't been noted can you use e85 or not? E85 would change the build and change what the mileage is going to be. also which is more important the mileage or the hp outcome?
"I'm not looking to race, but I want a reliable, S/C, DD that gets better mpgs that my GTO here on Fort Bragg..."
Better mileage would be my thought on this one, since he's got the goat for the horsepower needs.
