Tuning

My experience with:
4door, auto, 35's, 5.13's, at altitude in Colorado

There was very little performance difference between the ProCal and the Flashpaq 87 tune, though freeway mpg's went up about 1.5 mpg due to holding speeds better without the downshifts. After reading a lot of threads on the 91 tune, I tried it for a few weeks. - the performance and mpg's were worse than the 87 tune. Went back to 87. Then after reading a bunch or positive reviews of the tow tune, I finally tried it. By far the best improvement I found!! In addition to the performance gains, the shift points are changed and my unlimited is much, much more drivable.

The flashpaq is all about experimenting and finding the tune that works for you...

 

I'll drink to that!

 

I've got the Hypertech on my 07 unlimited. I am running the premium setting and am getting 25 mpg on the highway on 35s!

 

Ordered the AEV Procal from Northridge. Hypertech and Superchips do not have the 2011 info available and the release date is unknown.

 

Did you calibrate your speedo?

I maybe get half that mpg
