    There seems to be several people who are having issues with the program loading on their computer. The customer service is decent. They were able to install the basic tune on my programmer but I still don't have access to the computer program I need to load other custom tunes.

    Love it

    It was easy install, instructions completely dead on, no problems. The immediate power on the fly is incredible, all in all, I love it an highly recommend it.

    Great experience

    Worked just like it should have, I got all parts before I was supposed to which really helped. I will be using auto anything for things I expect to purchase in the future. Tuner works as advertised, got about 6mpg more after installing the GT platinum. Which is weird because the truck is so much more responsive and has way more power. Truck was always hard to start since installing the unit it starts first time every time. Not sure how it fixed problem but I like it!

    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.
