Narrative:

Upon departure from runway 13R at nqi; ATC issued aircraft X an intermediate level off altitude of 5;000 feet MSL at a climb altitude of 2;000 feet MSL and advised of south bound gulfstream traffic to the east of aircraft X's position at 6;000 feet MSL. The intermediate altitude was 2;000 feet less than initial clearance of 7;000 feet MSL. While in the non-standard left hand turn to MOA entry point and scanning for the traffic aircraft X missed level off altitude of 5;000 feet MSL by 400 ft. Aircraft X pilot made an immediate correction back to 5;000 feet MSL. Kingsville departure queried aircraft X pilot to confirm updated level off altitude of 5;000 feet MSL. Aircraft X was visual of gulfstream traffic during climb and left turn.
