I guess the flash tune I have on my PCM isn’t sophisticated enough to turn off the overboost code because I have definitely tripped it a few times. But there is no way to get rid of it with a different flash tune if I sent the PCM to somebody else? (I don’t want a piggyback chip) or would the OCR be the easiest way to fix it.

Someone like Jonathan at DTC could probably remove the CEL parameter, but as I mentioned earlier that would be a lot more expensive than an OCR like device.
You can see the actual mounting of the OCR in my SXE install video or images here or on Riffraff.

I cannot tell if you are upset about your experience or if you just don't care and moved on... Either way there is nothing I can do to help how you feel or correct the experience you had. Again, some people are happy with Jelibuilt, others are not. That is the way tunes go based on what I have read and seen myself on my truck. 1023 Tunes were great on my MST truck running medium tow when hauling heavy. Although, upgrade to the SXE turbo and now the same tune makes the truck run like it is on half power and under the turbo. I switched to PHP 65 HP Performance because I have a ZF6 and the transmission tuning is a non-issue for me, so I can try any tune I like without fear of the transmission shifting oddly. The PHP 65 HP Performance tune makes my truck run very well.
You should get what you pay for and be happy with it, but if the tuner is not responding, I don't blame you for moving on. Simple things like throttle responsiveness can be changed though. When 1023 approached me a couple of years ago and offered for me to try some tunes out free of charge, I took the opportunity. I ran 3 of the tunes and promptly removed them because the throttle response was way too quick. I told Dusty and he pulled back some of the responsiveness and made it more like a stock throttle feeling. I was happy with those for quite a while until they were underwhelming with the SXE turbo.
I hope you don't feel like you have to justify your tuning from DP to us because you don't. It is your money, your time, your truck and your driving experience. Stick with what makes you happy and don't let anything we say sway your feeling of happiness regarding the truck.

Which is exactly what I am doing. Moving on and condemning him.
I don't have to justify it but I am stating it for the completeness of the picture as to what was done to make it better and what Jelibuilt DIDN'T. I am willing to give anyone a shot at trying to fix it including going to Pure Diesel Power for an analysis so we can see if there is anything mechanically wrong BEFORE we end up changing everything from Stem to Stern and finding out it doesn't help. That is not the kind of diagnosis I work with.

I have used tunes from Gearhead, Tyrant and Cody that don't require a boost fooler.

Stinky suffered a lot of my growing pains with diesel, and I've had hot tunes that could push the stock turbo past 30 PSI. Drop in the bigger sticks and turbo with the same tuner that loves high cylinder pressures, and that was the end of my MAP sensor.
I went to an OCR and analog boost gauge (and a different tuner), and I have the same on Frankenstinky.

If no piggyback chip is in your future, a device like the OCR is the only way for you to fix it without going over budget.

edit: says he doesn’t know how to do that but wishes he did and just recommended a boost fooler.
I wonder if any of these other tuners can flash a single tune onto a PCM that fixes that.

Zero regrets going with the @Riffraff Performance OCR - Overboost Code Regulator.

That’s probably what I’ll do. I’m going to be making an order from him anyway for a Mishimoto coolant bottle so I’ll add it. (Old one finally started leaking.)

Then how do you get around the SES and defueling?

Which ones sell tunes that will boost anything over 25 psi AND don't set a CEL or defuel?

The primary goal you as an owner regarding a tuner should be how the tune makes the engine/transmission run at a given period of use and if you are happy with it when looking at several parameters and criteria.
If the CEL is triggered due to high boost and defueling occurs, get a boost fooler...
Done...
You are looking too much into it and are missing the point of having a tune.
