More Bully Dog GT Platinum Features

The Display Monitor

The Bully Dog Triple Dog GT Platinum’s 2.4” LCD full-color display is completely customizable to fit your needs. The tuner comes with two light settings: daytime mode and nighttime mode. These settings automatically adjust the brightness of the screen to the ambient light, making it easier for you to see during any time of day. You can change the color scheme and tailor the screen to display multiple parameters at the same time.

Easy Installation

The display monitor attaches to a universal suction-cup mount that you can attach to any flat surface in your vehicle. It firmly sticks to your windshield, your dash, or your window for simple viewing options. Bully Dog’s Triple Dog GT Platinum is a plug-and-play tuner that plugs right into your OBD-II port to upload tunes to your ECM.

The programmer comes with free Internet updates from Bully Dog’s website, so you’ll always have the most up-to-date software on your device. Your package comes with a USB-cable that connects to your computer to download the software and any custom-made tunes.

Read and Clear DTCs

The Bully Dog Triple Dog GT Platinum is also a diagnostic tool. When your truck throws a code, your programmer’s code reader option lets you read DTCs. If it is an easy fix, you can perform the work yourself. The GT Platinum also allows you to clear the code after you complete the work. This helpful program can save you money on a trip to a mechanic.

Pre-loaded and Custom Tunes

This programmer comes loaded with standard tunes designed to optimize your truck’s performance. These preloaded tunes give you better horsepower and torque for rough driving or towing situations.

They also calibrate your engine’s performance to provide the best fuel economy, saving you money at the pump. Each of these tunes has adjustable power levels, so you can tweak the settings to find the perfect combination of power and performance that you need. The preloaded tunes are perfect for stock trucks or vehicles with minor modifications.

The GT Platinum comes with three preloaded tunes:

  • Tow – designed for extra power gains required for towing over 5,000 pounds
  • Performance – a small increase in power and performance over stock settings; also compatible with light tows under 5,000 pounds
  • Extreme – provides the most power for fuel economy and daily driving; should not be used when towing

You also have the option to keep your truck on stock settings.

Each tune provides the following power gains, depending on your engine.

Results are based on Dyno testing and may vary with your actual vehicle.

Cummins Unlock Cable – required for 2013+ Cummins engines, which “unlocks” your 2013+ engine permanently. This means you can use your programmer on another truck as long as it is programmed with a GT Platinum tuner.
