Bought this to correct my speedometer and to get a little more power. I had to update the software on the programmer but after that it was easy to install and use. Good value.

pretty nice tuner for the money. a bit complicated without much info sent with the tuner to know what some changes are. iv had three different Hypertech programers over the years and feel this has a more noticeable power improvement.
