thoughts on sprint booster for N55? terrible throttle response.

Hey guys,

Ever since Feb. of last year after the newest software was updated my car has had terrible throttle response. We are talking I have to push the pedal down roughly 10-15% before anything happens. The car has been looked at by BMW countless times, including by a field service engineer, but to no avail. BMW even gave me the PPK for free, but it still did nothing to solve the problem. I absolutely love everything else about my car, but it is starting to spoil what has been an amazing ownership experience. So, my friend mentioned the idea of a sprint booster which is supposed to help throttle response...do any of you know if it will actually make a difference or whether it's just a waste of money?
