Using the most advanced gauge/tuners, users of vehicles powered by gasoline or light-duty diesel engines can get even more enhanced operational features and benefits.

Bully Dog’s Triple Dog Gauge Tuner (GT) offers advanced programming and monitoring capabilities, including the ability to easily change settings, even on-the-fly while driving diesel vehicles. This system is the equivalent of four products in one: a vehicle engine tuner, function monitor, performance gauge and diagnostic device, all in a single unit. In addition to significant horsepower and fuel economy gains, the GT provides a set of monitoring features and diagnostic functions for enhanced driving and safety, according to the company.

For example, if someone is running in high horsepower mode, and engine coolant or lube oil temperatures begin to overheat, the GT gauge/tuner will automatically recognize the condition and begin to lower the horsepower until the situation is corrected. The gauge/tuner will also alert the driver with a message on the panel display that notifies the driver what is happening and why (e.g. engine overheating, horsepower lowering).

Bully Dog gauge/tuners are installed quickly and easily by attaching leads from the control panel to the engine’s control module. Then vehicle-specific (Dodge/Cummins, GM or Ford in the case of these models) software is downloaded to a laptop or tablet computer via the Internet, and transferred to the gauge/tuner via a standard cable. The gauge/tuner monitor prompts the installer through the procedure, ensuring that software installation goes smoothly. After that, the user simply dials in the operating parameters that are required whenever desired.

Monitoring capabilities may be important to many vehicle operators, such as those with commercial applications or who frequently tow heavy loads. To ensure reliable, optimized performance, the more powerful gauge/tuners will monitor turbo boost pressure, engine RPM, transmission temperature, air flow, fuel rail pressure, and other operating parameters.

To ensure that performance and fuel economy are maximized, Bully Dog has a tool called Driving Coach available on some gauge/tuner models. Driving Coach is an on-screen feedback system that gives drivers specific tips on how to improve their driving habits in conjunction with their gauge/tuner capabilities to enhance fuel conservation while getting more efficient performance. This feature may prove highly valuable to commercial drivers with changing loads as well as those who use their pickups to tow an RV on weekends.
