  • The amount of mileage increase you will see when using the Bully Dog Triple Dog GT, # BY40410FL, is entirely dependent on how you drive, how well the vehicle runs and is maintained, the environment and other outside factors. The tuner itself does not alter the motor in such a way as to provide better gas mileage that you will be able to notice. What it does do is provide a mileage coach driving program that monitors your driving habits and grades you so you can see where you need improvement

  • Can the Rev Limiter be Adjusted Using a Bully Dog Triple Dog GT on a 2007 Chevy Tahoe with a 5.3L

  • Cold Air Kit Recommendations for a 2008 GMC Sierra with a 6.0 L and Mechanical Fan
  • The best option I can give you for a cold-air intake design on your 2008 GMC Sierra would be an AFE Cold Air Intake # AFE54-11071. The Bully Dog option that you referenced is only designed to work on vehicles with electric fans. The problem is that the aftermarket intake tube does not clear the fan shroud assembly. The # AFE54-11071 utilizes the factory intake tube so it will not interfere with the manual fan assembly.

  • Ability of Bully Dog Watch Dog Gauge Monitor to Correct Speedometer for Larger Tires
  • Because the Bully Dog Watch Dog is a monitor only, it is not capable of programming or changing anything on the vehicle, including the speedometer calibration. However, the Watch Dog does have a speedometer display function that can be calibrated for accuracy, see page # 23 of the owners manual, which I have linked you to. While driving, you would just ignore the speedometer reading on the vehicle and go by the corrected speedometer reading shown on the Watch Dog.

  • Improved Towing Performance Provided By Bully Dog Tuner and aFe Intake on 2000 Chevy Silverado
  • When combined with a cold air intake system like the aFe # AFE51-10091, the Bully Dog Triple Dog GT tuner would provide a noticeable increase in horsepower and torque, which will result in the engine pulling you up to speed more quickly.
