"Shipping was fast and installing was super easy. Put it in a 03 gmc 2500 hd. I had moderate gains on mid engine tune and havent tryed the performance yet. Transmission shifts are alot stronger and might be getting about 3/4 mpg better. Display is nice with lots of different choices on colors. I havent tryed towing with it yet but it is worth the buy." —Todd C from Saint Albans, VT bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2003 GMC Sierra, 2500HD, 6.0L V8.
