You'll get a better return on your money by having head work done. A tricked out or larger throttle body won't get you more than 1-3 hp and tq over a stock unit, if you get that much. Get rid of the V&H short ***** and grab a good 2 into 1 exhaust. Those two additions alone should gain you around 20 -25 hp and tq.

I do believe another forum member cdonis installed that cam and a 2-1 without head work or throttle body upgrade and got good numbers on his 103 with 111torque.

Yeah him and I had a convo when i first got them installed.

But i think the 2-1 exhausts are hideous so ill have to sacrifice some power for now.

Stock throttle body is good for about 115 hp. Not gonna get near that without headwork (and a different cam).
