I'm currently running 35's on my auto unlimited, and have 5.13 gears, CAI, exhuast and running my superchip with the 'tow' tune.
I feel I have plenty of power, get up and go, and consistant rpm's on the hwy and no downshifting. Obviously it's no V8 or Hemi, but I'm pretty happy with the result.
The gears and switching to the "tow" tune made a considerable difference. Even just switching from the "87" to the "tow" tune on top of the 5.13 was very noticeable.
As a result, my mpg's have actually gone down, mainly due to the fact that I can actually get up and move this large box at a reasonable rate. Obviously if I ever upgrade to 37's and start adding more weight, things will be different.
David at NR has suggested I give the sprint booster a try as well.
