I'm using the 87 tune. It has a little more power and shifts better. Gas mileage is around the same or a little bit worse. It was pretty easy to install.

The scan gauge does everything is said it would. Bought to monitor water and oil temps but watching the MPGs is really interesting and taught me some new driving habits. I did have one problem setting it up and customer service was fantastic.
