Bully Dog GT Platinum Tuner

Mileage savings

My 2010 f150 xlt 4.6l 3v went from 13 to 14 mpg to 16 to 17 mpg. Still to find out what kind of power I can get out of my truck using premium in tow/haul mode. Overall I am pleased with it. I like the driving coach so I can watch how I'm doing on the fly. It will teach you when to let off the gas and keep your speed without wasting gas. View more reviews...

Great product

Easy install, codes work well and so far I have been able to use the x-gauge codes for even more data. View more reviews...
