There’s no doubt that tow vehicles can always use a little help with horsepower and torque and the market for flash tuners prove that racers look for power when they need it and economy when they want it. Bully Dog’s GT Gas Tuner is a great choice for hauling and off-roading features, or improved fuel economy for long highway hauls. It offers space for 10 custom tunes, so you can dial in performance as needed. If you think that is all that the tuner can control, you would be very wrong.
Get ready for mind-blown. Depending on the vehicle and it’s options, you can control everything from auto door locks to disabling the traction control can be managed through the controller. You want a setting to control how long an accessory will remain on after the engine has been turned off and the doors closed? Bully Dog has you covered. Maybe you just want to run the high beams and fog lights at the same time? No problem. Maybe you just don’t like the key reminder buzzer on your truck. The Bully Dog GT tuner will allow you to change the frequency of the buzzer.
