The legendary Bully Dog GT Platinum Diesel Tuner is one of the most well-known and versatile products in the world of diesel performance. The Bully Dog GT Platinum Diesel will not only boost the horsepower and torque of your Cummins, Powerstroke, or Duramax-powered truck, it can also provide you with a wealth of information on the performance of your diesel. It does it all by combining the following four functions into a single, compact, do-it-all unit:

  • Programmer/Tuner to boost horsepower and torque
  • Engine Monitor to display a multitude of temperature and pressure data
  • Performance Testing to accurately measure and analyze ¼ mile times and more
  • Diagnostic Functions for troubleshooting and fault code scanning

Custom Programming Options

With the Bully Dog GT Platinum Tuner you can unleash the true potential of your Cummins, Powerstroke, or Duramax-powered diesel truck. Load up to 10 custom tunes on your GT device and optimize the performance level of your truck for specific situations or aftermarket equipment.

The Bully Dog GT Platinum Diesel features pre-loaded tunes to support stock or lightly modified trucks and can help you take advantage of performance accessories like as cold air kits, exhaust systems, or gear ratio changes. You can even quickly adjust factory parameters like speedometer calibration for larger tires, transmission shift firmness, engine idle adjust to maintain voltage needed to run accessories, and throttle sensitivity.

And if you have more complex modifications including but not limited to bigger injectors or a larger turbo you can have your local Bully Dog dealer create a custom tune file specific to your application.

Depending on the factory sensors installed in your truck, the Bully Dog GT Platinum can monitor and display the following data and provide you with most accurate information in one convenient location.
