I recently installed the Hyper Voltage System Type MR in my 07 350Z. My first driving impression was so-so. It feels like the throttle response is little more crisp. Of course this could be all in my mind to justify the $100+ i spent on it. I figure it couldn't hurt since the Z is drive by wire(electronic) instead of a cable. I also plan to install my own grounding wires in the near future.
