Very pleased with price and fast shipping.Instructions were a little vague for installation. I thought that I would be able to adjust transmission shift points at any time ,not just during initial install. overall I am pleased with product

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
