Here you go weiboy. You can purchase the boost sensor that way it will display it on the screen. Also you will not need the a/f box since it can read all perameters on our cars including the G37 and G35. That box is only a option if it wasn't able to read it from the ecu. So all you would need is the actual unit and the boost pressure sensor and you are done and be able to view everything you would want at alot cheaper price then the camp 2. Here is my source and I hope this helps
