GT Diesel Unlock Cable

Unlock the full potential of your Bully Dog GT Diesel Tuner with the Bully Dog 42214 Unlock Cable for 6.7L Cummins trucks. This essential cable is required to enable the ECM unlock process for 2013–2018 Ram 2500 and 3500 models equipped with the 6.7L Cummins engine. Without this cable, the GT Tuner cannot communicate properly with your truck’s ECM to apply performance tunes. Whether you're looking for improved towing power, throttle response, fuel economy, or overall horsepower gains, the unlock cable is a critical first step. Once installed, it allows the GT Tuner to provide access to multiple tuning levels, adjust transmission settings, monitor real-time engine parameters, and clear diagnostic trouble codes.
