    If it says saves on fuel mileage there wrong. I get about the same but the performance part is nice power and speed throddle response is quick. Have yet to haul or tow anything yet but main reason I got it was for the economy part maybe I need to screw with it more and find what works best cause they don't give you a manual on how to really tune it. All and all not a bad purchase.

    Screen is the right size.

    Fairly easy to download and install tuner. Screen large enough to easily read but small enough to not be obtrusive. Good menu services.

    I had the old model but it died. The 20ft is way to small and the controls are hard to use on the fly. It is hard to get to the program you want. I would much rather have my old one back. On tow mode it is not as powerfull as my old one!

    Works very well saw increase in horsepower and small increase in mpg. One fault the unit does not auto shutoff when engine is shut down. Believe this good be a theft problem but will see.

    Easy to install and like the look. The biggest reason I settled on it was the shift on the fly ability. I do a lot of towing and a lot of highway so this makes the transition much easier. Noticed a huge power gain coupled with my modifications.

    Did not work
