The throttle progressivity on my '20 Heritage 114 is totally different than my '14 Limited. The first thing I noticed is that the clutch engages the moment I start letting out the clutch lever. I don't know if it's because I'm still not used to the bike after riding a barge for so long, but the bike can definitely get away from you if you're not careful. So, to answer the OP's question, yes, I'm noticing the same thing as you're experiencing, but I've gotten better with more saddle time.

My 114 Fatbob's throttle is a bit choppy from 0% to say 15%...like a carb having a flat spot going from idle jet to main jet. Has taken some getting used to going back and forth from my Dyna to the Bob.

Yeah, that's a good way to describe it. Hopefully I can smooth it out with a different throttle map...

I've got the Heritage 114 and my wife has a 19 Street Bob 107. I noticed on my 114 while revving up through the rpm band that the torque curve wasn't smooth. I went with a Powervision (yeah, I know, warranty) and both the torque curve and throttle response improved. My wife's 107's torque curve while revving up is smoother than my 114 was and I haven't added a tuner to her bike yet. Is it perfect? No. Will I add the tuner later? Yes. But it was a little smoother than my 114 was.

wow....different world from my experience...just wow. Sorry to hear that. Maybe you have a loose connection or bad ECM. Maybe it needs a reflash.
this also kind of contradicts your first post...
originally you complained the low end had a dead spot and the higher revs were fine...
now you’re saying it seems to have more low end torque but less top end.
moving target, but addressing your Out of Breath problem...
There’s been a lot of comparisons between the 107 and 114 over the last two years and they all talk about the stock 107 maybe being quicker off the line, but nobody has ever said they felt the 114 had less on top. Certainly wasn’t my experience. Something sounds off.
Not sure where you are with miles and ride style, but these start very tight and take a good 1,000 to open up fully. Also your ECM “learns” based on your riding so it takes a bit of pushing the revs to wake up the top end fully. Start rolling it up to 4800 - 5000 before shifts on a nice ride. The ECM will start shifting engine delivery to accommodate. After that you should notice less “shortness of breath”.
regarding you’re power cam plans, I have yet to hear anyone love it. The torque cam on the other hand is a winner. Once it’s broken in it’ll pull like a bat out of hell from 1,800 to 4,800rpm. A little more up top wouldn’t hurt, but that’s an aftermarket cam or a stage 3...
the power cam doesn’t really start until 3,600rpm and you’ll lose low end.
best of luck

For those that say the SE tuner can adjust the throttle response, can you make it super touchy? I ask because my sports bikes are like this and I prefer a snappy throttle. Not that I think the current throttle is bad, but the initial 10-15% throttle doesn't do much, so I've been learning to account for that by getting well into 25% throttle before using much of the clutch. Not sure if I'm describing it correctly, but between the throttle and clutch, I can get the same torque/power feel between this bike and my naked/sports bikes but it's different due to the fact that the throttle takes more twisting.

My comment about running out of breath is just a general description of the engine. It feels like it likes everything about 1K RPM lower. My impression anyway.

My plan is to do the stage 2 now, and when it's close to saying goodbye to the warranty, spend more on full exhaust, real tuner, and an aftermarket cam. That way I get to feel an upgrade twice.
