Ok so after running a few tanks of gas this is my info on mileage, before Procal i was reading 13.6 mpg 2007 2dr with 35's and running an auto with 410 gears, now i am reading 17.79, my rpm's are at 1950 @ 65mph, the procal has helped a lot, although the mileage isnt great it is better, i also have a drop in k&n filter, the speedo is dead on, my mileage and speedo was checked using a fuel app and a handheld gps "not a stock navi", so i would say it did help out and i am happy with putting out the money for it.

Yeah, it changed the numbers, not your MPG or performance...it may say 13.6 but, in reality it is somewhere in between those two numbers...Your Jeep's CPU thinks it is running a much smaller tire, same reason why your spedo is off... Wish I spoke propeller head so I could explain it better.

esp good with a '12 and 3.73 gears. You can run up to a 35" tire with that ratio without too much worry on the '12's. For just .5" larger tire I'd save the $150 towards other mods.
