This is occurs because you are in the lowest throttle response setting. This is a feature of the F10 M5 and not a problem. The lowest throttle response setting is meant to make the car more comfortable and drive-able during every day driving situations. If you don't want that to happen select Sport on your Throttle Response button and the wastes gates will stay closed and you will get more response when you initiate throttle activation. If you want the maximum hair-trigger like throttle response when you are trying to drop your kids off at school, I recommend buying a Nissan GTR.
