Description
Increase Power and Performance. Further enhance the performance of your 2017-2018 5.3L GMC Sierra 1500 with the Predator 2 Platinum Tuner. The Predator 2 Platinum Tuner supports third party custom tune files and also 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 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 Platinum Tuner to see the full power potential your GMC can make.
User Adjustable. DiabloSport designed its Tuner to be user adjustable. This means you can make further changes to the tune files to suit your particular performance needs. Please note that not all adjustments listed below are available on all vehicles.
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 hundreds of dollars each year 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 your DiabloSport 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 Platinum Tuner is specifically designed for 2017-2018 GMC Sierra 1500 models equipped with the naturally aspirated 5.3L engine. This Tuner supports custom tune files, which are available separately.
