Software. My car used to do that when new. My dealer changed the plugs/injectors/and spark plugs - and updated the SW when my car was brand new. I never had that problem again. I actually kind of miss it though.
Then later when I got BMW anti-tuner SW update for the HPFP recall... that killed my throttle response and gave me that "lag SW" update.
Personally I would just live with this - its really not causing any harm. BUT if it really bothers you - you could have bmw do a SW update and take your chances with the "lag SW".
