+1... if you didn't adjust your tire size with the procal the mileage indicator on the dash isn't accurate (not that its much better after setting it up but it is closer)

Yep, nothing you did will improve your mileage. The procal will ease the pain just a little by recalibrating the speedometer.

I haven't recalibrated and don't drive on the freeway, with 35's and 2.5" lift I hover between 11.8 and 12.5.

Better than my Taco that I had.......Even with a bigger lift and bigger tires, the Jeep still seems to get better mpg....... My Taco seemed to weigh A LOT though *shrugs*
