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
edge evo brough my truck ( 5.4l Fx4) to life
After researching around I decided to give the edge evolution a try and I can say wow I'm impressed how much this programmer has helped my truck... my 0 to 60 improved by 1.5 seconds and still yet to figure out what else I can do with it.. gas improved as well I went from 13 MPG to about 16 now with messing around and doing my tests...
