I got about 2-3 MPG increase from superchips... More like 2 but can probably get up to 3 out of it... That's also using 91 octane though so it sort of evens back down cost wise...

to the forum.

The trick to better gas mileage for the JK’s is to keep the speed down to 60-65 mph on the freeway. Anything above and it just gets sucked right out of the tank like a kid with a flexi straw and chocolate milk.
