    I average between 16 and 17 mpg in the city.

    On the highway it's about 28-29.

    City driving only.

    Best numbers i pulled N/A on the highway were in the range of 28-30 MPG at 75 MPH.
    I find it odd that i get better MPG at 80MPH than I do 70MPH. Is there any reason for this?

    last i checked 50 mph is the most efficient speed.

    Faster should be worse, not better.

    Unless you change how you drive when you drive at those speeds.

    Drive the same all the time...keeping it around 2000-2300 rpms...except for when getting on the interstate/highway...i usually go up to about 4000 then just for the hell of it.

    I'm very interested in the tune that's getting you 35 mpg. I do well enough on just driver mod, but to do 7mpg better than me is impressive.
