Thought I would post this for folks. We drove from Colorado Springs to Albuquerque and back on Sunday to rescue a pair of Doberman's. I am running a 2012 JKRU with 5:13's, 37 MT/R tires, auto trans, Banks cat back, aFe cold air intake and TB spacer. We ran the speed limit, mostly at 75 mph. We averaged 21.2 mpg. Also, running 5:13 gears, I'm turning 3000 RPM at 75 MPH. The tires were aired to 40 psi.

yeah I know theres nothing by way of superchips, but "sounds like" they are further along with one for the 2012 than the 2011....i think they gave up on those poor guys!

Used the AEV ProCal. However, I also divided the miles driven by gallons used and came up with the same thing.
