Installing the programmer was a breeze. After installing on my truck I could feel the increase in HP and when driving the truck properly the mpg picked back up above what I was getting with stock tires (running 13.5x35s now). I had a question the day after installing the programmer and called the help line and was impressed with the help I received. The only negative is the overall size of the GT head unit. Could be a bit larger for visual aid.

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
