Narrative:

We departed runway 24 on the teb 5 departure. For whatever reason and despite how many times I had flown this departure; I mis-briefed one aspect of the departure and had it in my head that we were to make the turn to 280 at 4.5 DME versus making the turn at 1500 ft. Our climb was slower than normal as I reduced the thrust significantly for noise abatement and to better manage the aircraft. In leveling off at 1500 ft I had a feeling something was amiss; and had the first officer verify the procedure; he then clarified it was then that we needed to turn to 280. Okay; so we did that; we'd only been level at 1500 ft for a few seconds at that point. Immediately after was our check-in with departure control; and the first officer phrased it 'we're turning to 280.' well; true; but keep in mind we had only 'just' gotten to 1500 ft anyways. The controller then queried us as to which departure we were assigned and that we should already be on the 280 heading. At that point; we then were on the 280 heading; the first officer told the controller that appropriately. I almost screwed up that part of the departure; but we caught it and did it correctly. However; the controller may not have seen it that way simply due to our communication with him at the initial check-in. I had the feeling maybe he thought we were still on the 240 heading at 1500 ft for an extended period of time; which was not the case. Again; I'd pulled the airplane back significantly and had only just reached 1500 ft when I/we realized we needed to make the turn.
