Big performance increase. It shifts really hard. I am not sure if I like this or not. Gas mileage increased about 5%. I was hoping for more.

Intuitive interface. Easy to use. Made changes to tire size. Plan on a regear in the future. Was able to turn off TPMS. I was hoping to be able to create a increased idle setting for winching, but you must have the tuner plugged in when you want to increase engine speed. Did take a good 30 mins to flash on a new 87 octane tune. Did notice a little increase in throttle response, but not blazing.
