The Bully Dog GT Platinum diesel tuner is an engine tuner and vehicle monitoring device. Much like the PMT but a compact version, the GT has a 2.4" screen and unlike the PMT does not come with a pyrometer kit. The GT is designed to remain plugged into the vehicle's OBDII port during vehicle operation so it can monitor and display critical vehicle information such as exhaust gas temperature and transmission temperature. The GT can also modify certain vehicle characteristics such as speed limiters, transmission tuning and many others depending on your vehicle.

The Tuner feature adds power & economy mapping.

Performance Gauges
The GT allows the operator to monitor over 20 vehicle functions and parameters.

The Safety Monitor keeps track of vehicle temperatures and reduces horsepower when the temperature become too high.

Driving Coach - Increase Fuel Economy
This feature is designed to help the user drive more efficiently. As a Driving Coach the GT will give the vehicle operator real time driving advice in order to maximize fuel economy up to 37% (according to edmunds.com). It coaches the driver into better driving habits by providing real time visual and audio feedback pertaining to how efficiently he or she is driving. The Driving Coach also provides a "grade," on how efficiently the operator drove during a particular trip. This makes driving efficiently both constructive as well as fun!
