I remember a few years ago I was doing some work on aircraft MRO overseas, there were just literal trash heaps on fire all over the city that the facility I was working on across the chain link fence. That's when I realized no matter how much we conserve and try to reduce our carbon footprint, the rest of the world makes our effort at best, quixotic.
Exactly why I hate all this "green" crap. It's being forced down our throats, while we were already one of the cleanest countries in the world decades ago. Now we are being used as a guinea pig for the rest of the world. EV's and emissions forced on us while 90% of the world runs on vehicles with tech from the '70's.
And we have to suck our sodas through paper straws because Asia dumps their trash into the rivers:
A few years ago I think it was 5-star (but I could be wrong) compared a deleted and emission intact truck both with factory power tunes and there was no difference in power. If I can find the video I will post it.
so like an advertisement for their product?
if you don't care about emissions, which I do not, there is no positive argument for any of the deleted parts. None. An engineer starting from scratch and designing a diesel engine would never include any of it. They improve emissions and that's it. If removing them gave you the exact same performance it's still a win for eliminating pointless things that can fail and leave you stranded.
And if what you're saying is true and this difference in performance and mileage is strictly related to tuning, it's insane not to tune them this way from the start.
Also, if you believe the mileage gains are only from not having regen, that works out to about 18 gallons of diesel used for regen every 1000 miles. There's no way.

That's already here, tons of, uh, "follks" in CONUS now with straight pipe cars that haven't been registered in years, in CARB states, and not insured, and their neighborhoods look like that trash river already.
I am unfortunately stuck on the west coast with elderly parents that need someone nearby,. Here on our streets and freeways cars and trucks with no plates, no muffler, limo tint and driver probably riding dirty never get stopped, for "reasons".
But hey, the lazyboy warriors in the suburbs think if they just give up a few more rights, they are saving the world. These people live in their bubbles and haven't see how their apathy has already brought the third world here.

Power-wise, yes the same. Some say way more efficient. The raw numbers I've seen are only marginally better than stock. Not worth the delete/tune, unless you're having issues AND out of warranty.

Leave my leaf blower and weedeater alone!

We should have finished them off when we had the chance. Instead, we spent trillions to help them rebuild.

Im not advocating for deleting or not deleting, I'm just saying you get zero power gain from just deleting. The power gain comes from the tune. And most of that comes from different throttle mapping which can be obtained with a pedal commander. And the only mpg gain will come from not doing regens which is ludicrous to think it equates to 3mpg.
This *may* have been true in limited fashion prior to 2003 when diesels used mechanical injection and had no emissions equipment at all on them.
By 2003, GM had been running a the CP3 based fuel system on the Duramax for 2 years and doge joined the common rail party. Ford was the lone hold out with the last of the 7.3 and the introduction of the 6.0 but HEUI's are a far cry from a P-pump injection or other purely mechanical injection setup. Even the aforementioned 7.3 HEUI had been supporting multiple injection events since the 90's. IIRC the Nox threshold dropped in 2004, which effectively mandated the use of EGR, with Navistar and Ford's solution being a disaster but Chevy and Dodge have more success. Obviously the watershed moment came in 2007-2008 with the arrival of DPFs and more aggressive EGR.
That aside, delete tunes are still out there however the waters are definitely murkier with the EPA to continue playing whack a mole with shops and the Chevron doctrine augmentation hasn't seem to take the wind out of their sails with regards to going after shops. That said, even in Massachusetts (a carb state), it is surprising the mount of deleted trucks are kicking around, so it is definitely out there. Caveat emptor.
