lots of adjustments

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.

I have had my programmer for about 3 weeks now and like it. I have only had it in trans only mode so far to increase my mpg seeing how all I drive is highway. I have gotten just over 2 mpg better and that was with hauling a bunch of stuff in the bed. I didn't like that you have to remove a fuse to change modes, not sure if that was just to program it or if you have to do that every time you change modes. overall a good product and would recommend to anyone.
