Narrative:

Departing teb following TEB6 departure using FMS navigation. Departure states to fly heading 040 until 2.3 DME from teb then heading 280 climbing to 2;000 ft. We passed the FMS derived waypoint for the turn and followed the FMS guidance back to the FMS course. Turned left to a heading of 240 per the FMS guidance to reintercept the FMS course. Departure control questioned our heading and then assigned a new heading. While there was no traffic conflict; I'm sure the departure controller could see a future conflict on our corrective heading. Captain's over reliance on the FMS guidance and co-pilots workload contributed to this incident. This is a simple departure; 2 turns and 1 altitude assignment. We lost the overall objective of the departure blindly following the FMS guidance to correct our own missed turn given by the FMS.
