Narrative:

After departure from teb runway 24 the crew brief/actions were: positive rate of climb; retract landing gear; 400 ft AGL retract flaps; set climb power with autothrottles and engage the autopilot. With FMS LNAV; VNAV and autopilot engaged with the altitude capture mode annunciated on the RNAV 1 departure; the aircraft overshot the level off altitude of 1;500 MSL by 120 ft (1;620 MSL). As the pilot flying I used the 'touch control steering' mode to descend to and re-capture the correct altitude. ATC made no mention of the slight altitude deviation and there were no traffic conflicts. The previous model glf 5/V model I flew did not have any overshoot problems on this departure. It was a night departure and I had to engage the LNAV lateral mode after takeoff instead of having it selected before the takeoff roll. The aircraft was at a light weight and we used a high climb angle to alleviate noise at this noise sensitive airport. In the future I will more closely monitor vertical performance when using the VNAV mode.
