I am running the second setting economy/performance gain of 45hp. I just put on the Rolling Big Power exhaust. What a difference in response. At idle and cruising it is pretty much the same sound and when you get on it it sounds good. I will have more info on mileage when i get home from a 3000 mile...

once you get a chip or programmer you will never not have one again. I have the Bully dog on my 2006 duramax

I have a 2006 Duramax with the LBZ motor and i get around 15 city. my 37" tires hurt my mileage but the bully dog programmer has helped it
