IF YOU OWN A FULL SIZE TRUCK, YOU NEED TO GET A BULLYDOG!!!!Due to the performance tune bulldog will pay for itself in less than a year. I installed a Volant ramair intake with scoop along with the bulldog. @65mph I'm getting 19-22mpg!!!! And the added power and performance is a great! My trucks potential has been unleashed. I also tow a 3000 lbs boat. The tow tune makes towing a breeze. Mpgs drop with the boat behind me but, still getting better than stock. I've had this set up for a month now.
