do my dyno results sound right?

I got my car dyno'd and tuned and I made 287whp and 323lbs of tourque. I wanted to know if this sounded right with my combination. I was told my cam specs are:
Duration At 0.05 224 230
Lobe Lift 0.35 0.3735
Lobe Separation 112

im not sure which one they used. I was just curious cause the motor feels like it should have more in it and some times it hesitates a tiny bit when you open the throttle at low rpm. I wasnt sure if my cam and injector combination were too big for that motor.
