The bully dog is working great. I feel the power. My G37 is running good

Got this installed on my 2006 coupe after the intake, plenum spacer, headers, and straight test pipes into the stock catback. Car is a different ride! The power is nicely linear and I picked up 4mpg compared to my untuned ecru with the mods. Higher redline, no 0-60 training wheels, and all smiles here.

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
