Bully Dog releases tuner for CAT, Cummins engines

Bully Dog has released a new ECM tuner with four variations for CAT, Cummins, Detroit and Paccar engines.

The tuner can also read and erase trouble codes and adjust speed limiters, the company said. Users can choose between the Economy tune, Economy + Power or custom tuning.

The Economy tune can help drivers achieve mileage gains of 6-12%, Bully Dog said. By using Economy + Power, fleets can increase horsepower and torque up to 15% while still maintaining economy.

The device’s display makes it easy to read and erase trouble codes, adjust the speed limiter, and perform vehicle diagnostics while on the road.
