Loss of Power!

Couple of days ago I was pulling out of a parking space and the car stuttered for a second but was fine after that. However, after driving for a couple of miles I first noticed some vibrations on the clutch and then more significant vibrations on the gear lever and now I've noticed a significant drop in power as I accelerate. This is most noticable in 4th,5th and 6th gear, where before I was able to go down to 20mph in 5th and go back up pretty smoothly w/o downshifting, now the car shakes when I do that. It seems that the turbo is out or not giving enough boost.
I'm a little pissed because car only has 6.5K miles, hopefully BMW will be able to get everything straightened out the first time around.
Could this also be a sign of HPFP???

doesn't sound like a typical HPFP problem, could be a CDV problem? or you could have ruined the clutch, which, if you did I wouldn't tell anyone.

I seems the sound that the turbo makes is not there or barely noticable (hissing sound when you change gears - I think it's the blow-off valve that makes that sound - not an expert) but I was hearing it loud and clear before all this happened.
