Going up a hill making noise and no power was the exact thing I experienced on my '06. The '06 tour bikes were a transition year between Harley and the EPA, with cams with no overlap and a cat in the right side muffler. Following the advice in these articles, among others in the Amerian Rider tech forums, which, even though the magazine is defunct, can still be found on the internet:

I have a SE air cleaner with a Boyesen X Wing, with Stage One download, punched out stock Road King mufflers, and had the Andrews 21 gear drives installed at 30,000 miles instead of replacing the cam chain tensioners. After installing the cams, I no longer had any trouble with our local hills, but certainly struggled in the mountains with a lean condition. To finally finish what I needed to do, I installed fuel management using the new Cobra PowrPro within the past month. Here's a dyno chart just run two weeks ago. Note the Andrew's 21's have the torque right up there already by 2200 RPM, and continue to pull well past 4500. The engine is still at 88 with no other work. The A/F graph is showing the automatic PowrPro dialing itself in, but was pretty well set for WOT by the fourth pull.
The '06 parts manual (page 516) shows a stock '06 TC producing 59 hp and 71 ft/lbs. I'm now at nearly 75 hp and 78.67 ft/lbs. If I ever wear out the top end out I'll then install the 95" jugs.

After reading this thread, I'm sure I'm getting the correct cams for my 'desires'.
Will want adjustable pushrods. I see S&S has kit, as does Fuelmoto. Any advice on either brand....or another brand? I don't want to pull the heads.
I intend to do this myself. Good project for me. What speciality tools are needed? Anything I can rent from a auto parts place....Autozone and the like?
Thanks for any help. I'll appreciate it.

Here's what Andrews says
21G 10/30 220 255 .498 .134 Stock Bolt-in 88 cam: more torque for all around riding with
40/08 228 264 .498 .121 heavy bikes, intended for stock compression ratio and
21G cams run great with fuel injectors or carburetors! pistons. Similar to #23 cam in EV80. (1700-4800 RPM).
26G 11/35 226 262 .490 .138 Stock Bolt-in cam for 88-95 inches - stock compression ratio.
41/09 230 266 .490 .112 Great for two up touring, this cam will add torque and HP
26G cams run great with fuel injectors or carburetors! at lower and middle RPM ranges. (1800-5200).
