That's how it is supposed to work. Glad you got it.
do tuners "cheat" barrel harmonics or is there another way to duplicate previous barrel

You can develop for shooting at any fixed distance without a tuner. You might end up with a high SD load though.
Could just be that's your best shooting load.
But if you to work with powder node separate from barrel node, especially at a fixed distance, you have the option for lowest SD and best shooting results -with a barrel tuner. Then apply that with LRH, and at least you have a low SD load with a barrel hitting best at one distance. Typically still good at multiple distances (as needed for hunting). Depends on the barrel & system (like bedding).
So I could powder develop across a chrono for an ES under 10fps.
Choose a distance, like 300 or 600yds, dial the tuner into tight hot bore grouping, and eventually cold bore accuracy.
After that, there is no reason to mess with the tuner, or seating, or anything again for the life of that barrel.
It is either good enough, or it isn't.
For those who think a tuner should be optimized for atmospheric changes, that does not apply to hunting. That's point blank BR only.
After all, as a hunter, what would you fiddle with today -without a tuner? NOTHING
And from those in the statistic cult, who can NEVER be satisfied, simply ignore them.

I suspect that the barrel mass to tuner's moveable mass ratio is very important. Put a 2 oz. tuner on the 1.25" cylinder barrel and I too would doubt that it's going to have much effect. Put a 4 oz. tuner on a pencil barrel and now it should have some effect.

..contrary to an above statement, THEY NOT ONLY WORK, THERE MIRACLE WORKERS....Shooting under benchrest rules and conditions out to a 1000 we've found they preform miracle compared to nontuners, will never be without them on any of our comp rifles...

I have been hearing that for close to 20 years. But no one does it because it just doesnt work. Its a nice theory. But you cant tuner tune a barrel. It will fall apart.

I have not had that experiance. I can only go by my experiance and results. 40+ records and zero with a tuner. Thats not me trying to be cocky at all. Its just a fact I cant deny. And I have put on a lot of tuners. I have had more guys improve by getting them off tuners by getting them on. A lot of thats user error but thats a real problem thats hard to fix.

If you can make a non-tuner barrel shoot, you can make a tuner barrel shoot.
Same with a muzzle break.
Why make anything difficult about it?

I am refering to tuning for low es then adjusting the tuner for group. A lot of guys have tried that method. It doesnt work.

You CAN get a tuner that is too heavy as it will have a HUGE negative impact.
Years ago I was fooling with tuners on a 1.450" bbl on my rail gun. We put a big, heavy tuner on it and could not keep shots in a 6" group at 100 yards. At each shot you could hear the bbl ring until you reached up and touched it.

We did lab test them. We also published the controlled lab testing results in Modern Advancements for Long Range Shooting Vol 3, starting on page 57 ending on page 108. We fired over 1800 rounds in our laboratory testing.
In the end we found that marketing claims about the effectiveness of tuners improving baseline mechanical precision in rifles were not substantiated with thorough lab testing.
None of the testing indications that some find in small sample groups held up in large sample (100+ round) groups.
It was more common that settings indicated as "best" created worse shot groups, but not actually statistically significant by any amount.
We did find that adding weight alone without the tuner in some cases may provide benefits, and are testing further on this information. But essentially you could get the same results or better results by using a suppressor instead of a tuner, and would get those results in a number of the cases. But we are researching more into this now.

We put in the time to test nearly 2000 rounds on the subject in our state of the art lab....
Awesome! Who is "we"?
