Once i installed the BULLY DOG GT TRIPPLE DOG GAS TUNER PROGRAMER on my newerbody style 07 gmc sierra 1500, My mpg average went from 12 to 18. Instant improvement and performance. Not to mention the truck is lifted 7.5 in with 37 in tires. Easy programing settings takes minuets. The power the 5.3 puts out after my Bully Dog gas tuner was installed was fanominal. I will deff get my money back in fuel over about a year. Can't go wrong purchasing. This item. MUST HAVE PRODUCT.
