The throttle response of the M3 is the sure to turn off the sport button, which makes it worse. If you have any engine software like the Shark or Dinan, it again will be worse. I think that's one of the reasons BMW decided to have the transmission stay in 2nd gear until the car comes to a compete help stop the oscillations.

With experience, the oscillations will disappear. I have the Shark software and when I let a friend drive the car, he oscillated on every takeoff...experience is the key. Some people suggest resting your foot up against the center tunnel and then rocking/tilting your foot into the gas seems to help also.
