Good grief people! You obsess over a 1 or 2 MPG difference.

Re: mpg stock size tires on 4x4 7.3

For best milage just slow down and accelerate slow. Keep it below 2000RPM
and under 5lbs boost.

You will never recover the cost of mods for better milage. If you drive 55 you
will see fantastic milage, drive 75 and you will see very bad milage. If that
was your only concern you would have bought a Prius :)
