Its has to be the color creating the HP
Its quite possible your bikes a freak. I remember back in the day 3 of us had 650 Yamaha's and one of the 3 would walk the other two by a few bikes. The graphs from a few members have shown stock bikes putting out about 79-80 HP ATRW stock which I think is in the normal range.
Whats important is the changes you see from the Dyno + a/f ratio's before and after the tune. The 2 HP gain is what you would expect from the change in fuel delivery.
