Let's see if we can make it work.

I stayed at a Holiday Inn express

 

Actually, this isn't the egregious crime I might've suggested earlier. They are obviously more comfortable tuning with the PCIII or PCV, but they should at least be able to tune a bike equipped with SERT, which is a Harley product. Having to change tuners when you already have a very good one is unacceptable, IMO. I would still take it somewhere else.

I mentioned "low-end," which means low RPMs. TD's tend to hurt low-end performance compared to stock head pipes, all other factors being equal.

I didn't question your decision to change cams, but was asking why you chose the TW37's. Anyway, you already bought them, so go with them. It's just that the TW37's will like a bit more compression to retain torque in the low-end, but if that's not your priority they are a good choice. If I were in your position I would invest in a 4° advance gear from Andrews, as that will compensate somewhat for this characteristic if you retain the stock compression. You might want to call Andrews and discuss this with them.

Cam upgrades are very good bang-for-the-buck performance upgrades, but the wrong cam may not be an upgrade if the performance kicks in at an RPM that doesn't fit your riding style.

Most of us are not "grease monkeys," but the vast majority do a lot of tweaking. A cam upgrade is a fair exercise in the art of tweaking, but it can be done by almost anyone who has a moderate array of tools and can read the service manual. I would accept one of these generous offers to help you do the job and go for it. The experience is something you will not forget.
