This could be due to the software on the car which adapts to your driving style. Drive the car aggressively from when you start it first thing in the morning. You will find that the car will be much more responsive during the day. Especially if you include a couple of WOT runs. If you have been taking it easy on the car I've noticed that performance does take a hit until you teach the car what your intentions are. I'm sure others have noticed it as well. Just giving some suggestions, not sure if this is your problem or not.
