"Though this tuner is quite expensive I found that it was very easy to install, and helps tremendously with the driving ability of my truck. I have noticed an increase in mileage (about 1.5 mpg) which is helpful! The screen gives a lot of detail and I think it is worth getting." —Andrew M from Yukon, OK bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2001 Chevy Silverado, 1500, 4.8L V8.
