Reason why N55 is not that responsive to the throttle is because of the valvetronic system and the turbo system. It is normal for it to be laggy. I had valvetronic sensor fail on my engine and computer defaulted to all valves being adjusted for maximum lift and engine controlled by the throttle butterfly, this instantly gave me instant throttle response.
