Narrative:

We departed teb runway 1 via TEB6 departure; initial altitude 2000 ft; 40 degree heading until teb 2.3 DME then left to 280 degrees. Landing pilots were reporting windshear on final. I was in the right seat; pilot not flying; handling the checklist; etc. The captain was hand flying the departure. It was very turbulent on takeoff. After raising flaps and contacting departure control; I called out the DME reading until 2.3 then set the captain's heading bug to 280. Departure commanded a heading of 270. I set the pilot's heading bug then checked for compliance with the procedure. I noticed that the aircraft was climbing through 2300 ft. I do not recall hearing the altitude hold annunciator; so it may have kicked off for some unknown reason. I alerted the captain to the deviation and he corrected the altitude immediately; but not before we ascended another 100-200 ft. The captain immediately returned the aircraft to 2000 ft. ATC noticed the deviation and asked us to report our altitude. By this time we were back within tolerances so I reported '2000'. All of this occurred within 10 to 15 seconds. To my knowledge there were no other aircraft within the immediate vicinity. My TCAS screen was set on the 5 mile range; and I did not see any targets at the time of the event.
