Works great!!!

I lifted my truck and put bigger tires on it so I needed to adjust my speedometer and this works perfectly, and the part that scans codes and clears codes work great also.

2008 F150

Reviewed By Charles B (Greensburg, PA) Reviewed for a 2008 Ford F-150 —9/15/2014 10:55 AM

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.

Does nothing

Reviewed By Kirk F (CUMMING, GA) Reviewed for a 2014 Dodge Challenger —8/26/2014 6:54 AM

I sent their tech-support an email explaining lack of any positive results. They never responded. There is no better MPG and no better throttle response.
