There is no need to use more mapped points. Tune it just like you would an S550 Coyote mustang or F150, just not as many mapped points basically. Same logic.
The logic for the Godzilla is basically the same as the F150 except it doesn't have DOHC. If you can tune a coyote you can tune a 7.3L.
I remote tune GM stuff every day. Send me a PM with the details

Old MPVI functionality with Windows 11.
If your laptop is running Windows 11 and will not let the MPVI drivers install or work properly due to being unsigned with Error 39, this is the fix.

Post your log. Desired lambda will move to give you the target fueling, just how the logic works. Sounds like its fat and needs leaned out some so the closed look isn't doing the heavy lifting.

The IAC isn't the issue here, it's behaving as it should. It will need additional air to startup. It sounds like you need more hot afterstart enrichment and delay.
I've done a number of these and never noticed this issue so not sure what is going on but of course its not working right on a family vehicle.

copy/paste injector profile from LT4 vehicle
Its not as simple as flipping the switch with a P59, they need a segment swap from a flex fuel vehicle of the same OS (flex avalanche or tahoe should work for your OS) or user defined parameters.

Put a fuel pressure tester on it and make sure you've got good pressure throughout the rev range.

Without seeing a datalog it's hard to say, but I bet you've got a mechanical issue more than a tune problem. What I provided should have ran very well, and the sound from the video doesn't sound like...
I do hope you realize that most of the hard "lope" you're expecting to hear isn't typically the natural sound of the engine and exhaust setup. Most of the lope you here in LS engines is intentionally...

Those trucks are bad about communication issues. If it has an aftermarket radio, steering wheel button interface box, or alarm system, those are notorious for causing those issues. You can try...
Multiply transport delay by ~1.25

If that doesn't run halfway decent, you probably have a mechanical issue
Unfortunately, Ed passed away several years ago. Throttle up industries bought out his business and is selling it under their name now.

Just not connecting the dots correctly. I had to read it a few times to get it as well. The PCM is inferring a MAP. What you're doing is adjusting the values in the calculator based on actual load...
That just means the hardware was for V8 and V6.
As Bill said its likely tunerlocked. There are ways you can try and get around this by grounding a pin on the board inside the pcm....
The supplied MPVI2 cable that came with mine was bad after 2 weeks. Switched to a really nice Anker brand USB C cable and haven't had any issues. I would get detect protocol errors sometimes and...
