Troyer can write "fuel efficiency" tunes for the Xcal 2 or Xcal 3. I believe it's possible to set the Edge for fuel efficiency as well, but you really need to know what you're doing to avoid running lean.

I know that Troyer says you'll see at least slightly better mileage even with his performance tunes, and I don't doubt it. The problem is that with the performance tunes I can't keep my foot outta the throttle! LOL..

Maybe someday in the not-so-distant future I'll calm down and drive like I should. Though actually even with a lead foot my mpg hasn't gone down by more than .5 mpg.

 

Mike has my truck getting 16 mpg on the highway with the best of 3 different 93 octane tunes. Not bad considering it is a built 4.6L motor with a supercharger running more than 12 pounds of boost .
