The bullydog has not lived up to any hopes for me to improve mpg. But first of all, the package says you can change on the fly. Well you cannot and it takes 7 minutes to delete or add a program. So if you want to experiment, it takes 14 minutes to change to a different program. Secondly, the unit is so small that it is a struggle to read the info. Lastly, there was absolutly no change in mpg, there was more pep for sure, but that is not what I was looking for. I will be returning this unit.

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.
