Is this easily added after the car is built? If you're going to tear into the dash for the glove box it might not be too bad, be sure to leave space for the heat ducts behind the box. The space up there on mine was horribly crowded with the box and ducts and that is where they chose to mount the DFI controller. It was very tight.
