Keep in mind that you have a counterbalanced engine which eats some power on both sides, so your numbers will never be as good as a touring bike motor. But, those numbers do sound low. As mentioned, with today's engines and closed loop operation, there is no "best" A/F ratio, as Jerry mentioned. One of the guys familiar with that cam will hopefully chime in and talk about the cam and it's compression needs, if any.
If you have the pro tuner...who did the tune? Did a HD dealer do the cams and "tune"? If so, do you know for a fact that they actually tuned the bike or did they just stick a map in it? Just because a shop has a Dyno is no indication that they have someone competent to operate it. I'd say find a good tuner, even if you have to travel a bit to get to him.
