Q: How does the Power Pup work?
A: The Power Pup reprograms the engine computer (ECM) with engine tuning modifications. Bully Dog's engine tunes are designed to improve the engine's efficiency; the result is improved fuel economy and increased horsepower and torque.

Q: How many tunes are available on the Power Pup?
A: There are two tunes available: an "economy tune" and an "economy with power tune".

Q: What does the economy tune do?
A: The economy tune primary purpose is to improve fuel economy without changing a lot of other parameters on the vehicle. Fleet managers are generally choosing this option because they don't want their drivers to know that anything has changed on the truck, but both owner/operators and fleets are using both tunes with success.

Q: What does the economy with power tune do?
A: The economy with power tune is geared to improving fuel economy while adding extra horsepower for pulling large grades. The economy with power tune adds about a 15% improvement in both horsepower and torque to the rear wheels. Generally, owner operators are using this option.

Q: I'm installing an a Volvo chassis into a Cummins ISX. Do I need a Cummins adapter cable before I do the install?
A: Yes, we highly recommend that if you are installing on a Cummins engine that you have the adapter cable. Volvo is known for having a lot of communication on the bus and that interrupts the installation and sometimes stops it completely. The cable will allow you to bypass the dataport connect and plug in directly into the ECM.

Q: Can a customer switch between the economy tune and economy with power tune?
A: Yes, customers can switch between the two tunes as well as return the vehicle to stock. See the product instructions on how to change the tune.

Q: Can a customer load a fuel economy tune on the truck themselves or do they need to use an authorized Bully Dog dealer?
A: If a customer is comfortable with electronics and computers, they are more than free to do the install themselves. We recommend that if you aren't comfortable that you let one of our trained authorized dealers install one of the fuel economy tunes onto your vehicle.

Q: Where can I purchase the Big Rig Power Pup?
