I have had my bully dog gt tuner for about two weeks and my reason for buying it was gas milage . I own a 2007 GMC crew cab with the 4.8 V-8 in it,my truck has 22s on it so the truck only gets 13 miles to the gallon . After i installed the tuner it gets 16 miles on regular gas and 17 miles on prem. I still can`t believe that it made that much difference, you will need to keep your foot out it ! Overall i am very pleased and i highly recommend bully dog. Thanks Bully Dog, worth every penny !
