Easy, took just a few minutes to program and what a difference it made in acceleration! I haven't checked the mileage, but it doesn't matter much.

The Hypertech tuner is easy to use, but not all the options were available during programing. The 350Z is stored during the winter, but I did have one nice day to try out the new tune and make sure the car was running right. The throttle response is sharper and the car does seem to be a little quicker, but I won't know just how much improvement there is until spring. I was impressed with testing of the product that Hypertech does and is one of the reasons I bought the tuner.
