My thought on the matter is that a PC is a great way to mask an existing problem. But there may be two things going on here:
1) You are hearing experiencing normal Victory things and coming off another bike you're not used to it and haven't been informed about "normal" Victory traits, like a small decal pop on certain years and setups. A PC won't help this.
2) You bike has a problem (intake leak for example) and you dealer(s) isn't smart enough to fix the bike and instead wants a blanket band-aid: the PC. The PC won't help this either.
Your setup is very mild, I see no ready for a PC. But we're going to need more info: year, model, history.
