The tuner was super easy and simple to install. It literally took minutes to install. Performance increase is very good with sharper shifts and higher torque The mileage increase is better by a few MPG, but I have a hard time keeping my foot out of the throttle. I would suggest it to anyone that want "bolt on" performance. This is the second superchips tuner I have purchased and these guys know how to do it up right. They will even offer tech help on the phone if needed.

I praise Autoanything for the great prices for name brand products they offer. The Jet Performance Programmer did everything advertised. I am happy with the results. Autoanything needs to speak to its vendors who apparently move its defective product to Autoanything making Autoanything bad. I've had to send back three items to Autoanything because of bad poor quality or workmanship...not the fault of Autoanything.... Autoanything kept its promise.. Went extra mile of replacing every item..
