Summit sport mode...
If you haven't put your jeep into sport mode yet - do it - and - do it on the highway! All I can say is wow - and - I get better gas mileage. Just shift in and out of it on a flat stretch of road - my MPG goes up when in sport mode. The power is incredible - while I have the Hemi - I'm very impressed with sport mode and the way the Jeep hugs the road on acceleration - especially turns etc.
