Vacuum readings

What are the typically expected vacuum readings for the S1 Exige engine?

In my VHPD engined Exige the vacuum reads about 60kPa when idling. Compared to a standard Rover K enige this is quite high and may be caused by the high-overlap camshafts.

Thanks trackrod, I managed to hook with the wifi reader and the Car Throttle Ap yesterday and got some readings, similar to yours really 64-66kPa
