not worth the price

I purchased my tuner 2 months ago with the hope of increasing my gas mileage on my 2001 GMC 2500. Bully Dog packaging states that you can increase your mileage by thirty percent, I am lucky to be getting ten percent, and I think that is due to the driving coach. I have tried different tunes with the same result. If your buying a Bully Dog tuner for gas mileage increase don't waste your money!

Downloading the program from personal computer to the tuner was a little complicated, but the set up in the vehicle was easy. It does make a difference in performance, at least with shift points and acceleration are smoother in performance mode, which could be less desirable if you prefer the harder feel of acceleration pushing you back in your seat with a stock G37. Upper end torque is increased, giving more passing power at higher speeds. Overall it's a good product
