I wouldnt worry too much about that man.
Like i said and others said, dyno's on different days = hard to really compare back to back, unless you run them at some super awesome facility which can control air temps, humidity etc etc. But even then, they could be diff everytime you go back.
For example, if you went back this weekend and just got a dyno, your numbers would be diff. Heck ask em if they will give you one or 2 free runs just to see that out.
One decent way to see how your numbers line up is to go to a dyno day.
2 years ago when we did a dyno day, all the stock Z's posted up numbers within 3 whp of each other.
