Best deal I could find for this product. Product performs great and I couldn't love it any more.

Up to 9 gauges at once and easy to use. Best part is you can check your check engine lights and clear the codes. And has a good maintenance reminder on all a wide variety of maintenance for your truck. The only thing I am not sure about is unplugging and replugging it in if it saves your data.

I needed the Diablosport tuner to turn off my obnoxious AFM, and it did as promised. It also delivered harder shifts and more power even in the mildest tune. The surprise was that my Sierra now has an extra 30 minutes of highway range due to more MPG.
