IMHO you can't really say that the combo is making less HP than it should. I know a lot of guys say that a X bike with cams, pipes, air filter and tuner should be making 115 & 115. But the only time that I'm seeing those numbers are on Kyle's or Lloydz Dyno. I don't think you can put much stock in comparing dyno figures unless they are done on the same dyno. For example, Kevin's dyno numbers are consistently lower than Kyle's or Lloydz but that is due to his dyno reading lower than others. A dyno is just a tool used to tune a bike. The specific numbers off of the dyno make little difference.
For example, I put the whole performance package on my brothers Vision (HP cams, D&D's, Lloydz Filters, ATS, PCV) and had it dyno tuned here locally. His bike only dyno'd at 114 HP & 110 TQ. Most people would say that is low for a Vision with all the performance goodies but the bike runs like a scalded dog. If we put that bike on a more generous dyno it would probably pull 120 HP.
I'd definitely add the ATS because that's the best performance mod that you can do for these bikes. Other than that ride the bike as is and see if you like it. There is probably 5 HP to be gained with a PCV and a better set of slip on mufflers. But, I'd ride the bike for a while and see if it's worth it to me to spend the money.
