I am very happy with this purchase. I have the 3.6L Pentastar engine. I changed tire size and needed to update so the speedometer and odometer would be correct. The tuner gives a nice increase in power and throttle response as well. I am running the 87 octane tune and have tried the 93 octane tune. It is a noticeable difference, but I did not want to spend the extra for fuel.
