Great results - I am at this very moment having brainstorm as what to go with (cam, 122, 124, 131) and this graph might cost me a few dollars 🙃
And with this being said, I wish you had another cam in there 😉
The tune was done at the dealer using Power Vision 3.
Regarding the cam.. funny story about that. I am investigating cams as well. The original plan was to do the Stage IV with Screaming Eagle everything, including the tune; in order to keep the factory warranty and take advantage of HD extending the factory warranty to all of the added components as they were installed within 60 days of purchase. Two issues cropped up.. first, I had a California VIN. Motorcycle purchased in Washington, I live in Washington. There are no tunes available from SE for California VIN motorcycles. Second, I had a cracked rocker arm already.. 1K miles on a stock 114. My goal was to get some more power while keeping the engine relatively reliable. I am ok not getting cutting edge power if it prevents the headaches that can come with it.
Had I gone in with the original plan being to trash the warranty, I may have gone with different parts!

CALIFORNIA VIN?!
Didn't know anything like that exists!
RPMs is indeed RPMs, but NM is not ftlbs. Inserting different units of measurements in a numerical graph will yield different curve heights, even though the torque is the same. You seem to have grasped the concept when it comes to dick size, yet you've applied it backwards when it comes to torque curves. The torque will be the same, yes. But representing it on a graph using two different units of measurements will result in two different curves, even though they describe the same thing. Just like the dick sizes would look different on a graph when inserted in a uniformely scaled numerical graph that doesn't have its own specified unit of measurement.
These three dicks are the same size, but since they've been measured using different units of measurement they look like they aren't. Just like a torque curve using NM will be higher on the graph compared to the same torque measured in ftlbs.
Get it now?
Damn! Seems like I have missed a lot of fun here!!!
Did he understand eventually? 🤣🤣🤣🤣
Here's my 21 SGS with SE 131 Stage 4 kit, SE Extreme Ventilator AC, FM XXX 2/1/2 header, SE Street Cannon mufflers and PV tune. All kit components as supplied including SE517 cam.

So these fine numbers from that "overpaid thrash" SE stuff?
Interesting!

Yes, all overpaid trash SE stuff. For me adding a cam to gain about 10+ hp/tq is not worth it. The bike goes good and driveability with the SE517 cam is perfect. Cruising i am getting over 40mpg as well with this setup. Muffler choice is really important with the XXX headpipe.

I have not tried different ones but I discussed with FM st length before purchase of the XXX. Also did research and mufflers that ste too open will impact low rpm torque.

Im in the process now of building a 131 for myself. I plan on using the same FM xxx head pipe with the FM Street Outlaw mufflers. It worked well in my 124
