Human Factors
Climbing out on BLZZR4 departure out of BOS Runway 22R was given a climb from 5;000 feet to 6;000 feet. Shortly thereafter departure turned us off the SID to a heading of 190. While in the turn I noticed I was approximately 250-300 feet above the assigned altitude of 6;000 feet. Started to make an immediate correction but entered some wake turbulence of the preceding aircraft and our altitude got to approximately 6;450 feet and airspeed was 15 kts hot. We made an immediate correction back to 6;000 feet and corrected the airspeed deviation. No other excursions occurred. ATC never contacted us or mentioned anything.
B767 Captain reported that distraction resulted in an altitude and airspeed deviation.
