First thing I'd do is check ATA, brace heigth, and make sure the strings and cables are at their correct length. 75# is a bit over what I would want with 70# limbs. If that all checks out, I'd look at the cam timing. I also think that 327fps might be a bit optomistic for that arrow weight. Also, what do you have on the string (D-loop, silencers, peep, etc.)? All of those slow down a bow. Give us all the info you can about the bow, and I'm sure others will pitch in too. As far as the limbs being tight in the roto cups, that's normal with the new style. Mine are a very tight fit.
