Easily tune your diesel engine on the fly and monitor vital data with the Triple Dog Gauge Tuner. The full-color, customizable screen lets you monitor up to four different parameters at once. In addition to these parameters, the screen also features a large display that can be customized to show one of three different gauge styles (analog, analog with mini-graph, or full graph) or the Driving Coach display.
Get more horsepower and torque with the press of a button. On-the-fly adjustment means that you can go from OEM settings to extreme power in a moment's time. Choose from four different power levels to fit your driving needs.
| Power Level | Gains | Application |

| Extreme | Up to 120 hp Up to 240 ft-lb | Maximizes power Intended mainly for racing |
The GT tuner lets you monitor more than fifteen different parameters so that you can be aware of the function and performance of your Chevrolet Silverado at all times. Set parameters quickly and easily through the Gauge Setup Menu. Note: Not all of the following are available for all applications.
You can monitor up to four parameters at a time, with each displayed along the left side of your screen. To view detailed information about any one of those factors, touch the button next to it, and the large gauge area on the right will display the information for that parameter.
Running the Driving Coach program turns your gauge display into an information hub for tracking your fuel economy. Monitoring the information presented here will give you a good indication of how your driving habits affect your fuel economy and overall engine performance.

The Instant Fuel Economy graph shows real-time fuel usage. This can be displayed in either miles per gallon or kilometers per liter. The Wasted Energy graph shows your acceleration and deceleration in relation to a base centerline. The centerline represents zero wasted energy. If you accelerate or decelerate too quickly, a color bar will extend out from the centerline, so you can see how much energy that move just cost you.
The Report Card graph indicates your overall engine performance and fuel economy, and it ranges from "A" for optimal performance to "Epic Fail," indicating the need for a tune-up, as well as a change in driving habits.

If you're not interested in fuel economy and are really only in this for the extra horsepower and torque, you can remove the Driving Coach from your monitor and instead view a large gauge of any chosen data.
