i got one for my 06 1500 reg cab long bed with the 4.8 in it, i love it. i jacked mine up 5 inches and running 35s. was getting about 14mpg before it and now about 16 driving how i normally do, (not light on the gas). my 0 to 60 before was around 11 sec, now its between 8 to 9. but i feel like i had one of those great engines right from the factory, it was already spunky, now i just love it, makes the front of my truck hop. if i drive it real nice on the thruway, i can get about 18 to 19. i also have a cold air intake and no muffler, so im back up to what my truck was when i bought it mpg wise, which is nice considering all of the stuff ive done to it.
this pic is with 33's
a day of fun in the mud
its really hard to believe how short my truck was, i love the hd look, so i went for that, i didnt want 11 to 12mpg.
anyway, i would def say the bully dog was worth the money
