Narrative:
Departing teb airport on the teb 5 departure runway 24 we were cleared for takeoff and we departed; gear and flap retraction were normal. At approximately 500 ft I reduced power for noise abatement and we were given a frequency change to ny departure control. I leveled off at 1500 ft. Very shortly (less than 1 minute) after the frequency change and just after leveling off we were given a climb and heading change. The controller came on the radio to ask us our altitude. We said 1600 ft. He said he was showing 1900 ft. This is not what our equipment showed. I feel that things are happening very quickly at this time and as soon as I heard the climb clearance I continued the climb and maybe that may have caused the altitude discrepancy.

Title: AN HS125 DEPARTING ON THE TEB RWY 24 SID LEVELED AT THE 1500 FT CONSTRAINT BUT WAS QUESTIONED BY ATC BECAUSE THE XPONDER WAS INDICATING 1900 FT.
Narrative: DEPARTING TEB ARPT ON THE TEB 5 DEP RWY 24 WE WERE CLEARED FOR TAKEOFF AND WE DEPARTED; GEAR AND FLAP RETRACTION WERE NORMAL. AT APPROX 500 FT I REDUCED POWER FOR NOISE ABATEMENT AND WE WERE GIVEN A FREQUENCY CHANGE TO NY DEP CTL. I LEVELED OFF AT 1500 FT. VERY SHORTLY (LESS THAN 1 MINUTE) AFTER THE FREQUENCY CHANGE AND JUST AFTER LEVELING OFF WE WERE GIVEN A CLIMB AND HEADING CHANGE. THE CTLR CAME ON THE RADIO TO ASK US OUR ALTITUDE. WE SAID 1600 FT. HE SAID HE WAS SHOWING 1900 FT. THIS IS NOT WHAT OUR EQUIPMENT SHOWED. I FEEL THAT THINGS ARE HAPPENING VERY QUICKLY AT THIS TIME AND AS SOON AS I HEARD THE CLIMB CLEARANCE I CONTINUED THE CLIMB AND MAYBE THAT MAY HAVE CAUSED THE ALTITUDE DISCREPANCY.
