I have a 2010 JK Unlimited Rubicon with stock tires and recently installed a cat back exhaust and Valont cold air intake, Also picked up a BullyDog GT and I was wondering how others have set it up for best fuel millage for highway driving. Any help would be appreciated.

 

I just run the regular tune. I didn't feel much of a difference when I tried the premium tune, and the mileage was about the same, so it's not worth the extra $ for premium fuel. The trail tune is good off road though. I've got a manual 2dr w/3.73s on 35s and I get about 17 highway and 12-14 in town, depending on how I drive it. I've got the same intake and a Magnaflow system that cuts off in front of the rear axle. I really like how you can completely shut down the traction control system.
