The Hypertech tuner required an online update prior to installation. It was easy to update, but would be helpful to know prior to purchase. Some noticeable power gains and shift firmness. Will have to drive a while before I can comment on the fuel mileage increase. I have used this product with another one of my vehicles. On an F250 superduty with a 6.8 v-10. I saw a 3 mpg increase on highway mileage. No increase in city mileage.
