I have a 2010 3.8l v6 jeep wrangler in manual running 35's. The jeep has plenty of power but accessing it is not possible leaving the car feel dead. When I installed the hikeit it changed the access to power and transformed the car. I primerily off road in the desert and snappy power is key. The instant throttle response gets you out of trouble. before i would have to wait for the engine to rev up and by the time that happened the car would of run out of momentum and suffocate. Now I can pop up a dune, instant access to the power that was there all along. In town and cruising I put it in eco mode which is fine for lazing around. I use this with the superchips performance tune. Before I was seriously looking at a supercharger, now I feel I have as much power as I need. In short its turned a restricted engine into a beast. Very happy. Only issue is in the auto setting on the hikeit the car will not start, like its starved for fuel, turn it off and away she goes.
