Diablosport Predator 2 Tuner (07-16 6.6L Duramax Sierra 3500 HD)Find parts that fit my vehicle

Increase Power and Performance. Further enhance the performance of your GMC Sierra 3500 HD with the DiabloSport Predator 2 Tuner. The Predator 2 Tuner comes preloaded with Diablosport's very own pre-configured tune files. When your Sierra rolled off the assembly line, GMC programmed it to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in the search of more power. So, if your 3500 Sierra is bone stock, or if you have added a cold air intake, throttle body or exhaust mods, you should invest in a Diablosport Predator 2 Tuner to see the full power potential your GMC can make.

Adjustable Parameters. The DiabloSpor Predator 2 Tuner features end user-adjustable parameters so you can further customize the tune to maximize the performance of your modifications. These parameters can be adjusted on DiabloSport Pre-Configured Tunes and/or the stock tune. Please note not all adjustments are available on all models/vehicles.

Internet Updatable. The Diablosport Predator 2 Tuner is internet updatable, meaning you will just plug it into your laptop or desktop computer with the included USB cable, then visit Diablosport's website to receive the latest firmware updates.

Data Logging and Monitoring. With a full color, high-definition, 2.8-inch screen, the Diablosport Predator 2 Tuner makes it easy to read the Built-In Data Logging and/or the Real Time Data, so you can view popular sensor data such as Speed, RPMs, Air/Fuel Ratio, Spark, Boost, etc.

Diagnostics Tool. The Predator 2 Tuner can also be used as a diagnostic code reader. Save yourself time and money by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.

Easy to Load; Easy to Restore. When you load a tune on your Sierra, the tuner automatically stores your vehicle's factory settings. To return to the original factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done. This is ideal for visiting dealerships for warranty work.

Application. This Diablosport Predator 2 Tuner is designed for use on 2007-2016 GMC Sierra 3500 HD models equipped with the 6.6L V8 engine.
