2023/2024 6.7L Powerstroke MAX safe boost

Just curious.
What is the MAX boost, that the 2023/2024 6.7L Powerstroke can safely support ?

Assuming that you address all the problems outside the engine. You make sure:
- the injectors & fuel pump can keep up with the demand
- you can cool the engine, the air, the oil, the turbo etc.
- back pressure stays close to 1:1
- turbo can create that boost
- etc. - you address any other EXTERNAL problems that might arise.

What will be the MAX boost you can feed the engine before you start to have issues with a STOCK ENGINE ?
LIke: blown gasket, bent rods, cracked piston, rings etc

Even better, maybe you have an opinion on what will fail first? And at what psi ?
Of course this is not an exact science, so I will take educated opinions.
Or, you could just answer the poll.

40 psi since the gauge only goes to that. After that I believe you run the risk of lifting the heads and causing blown head gaskets,

Because this is a forum. People come here to ask questions, share opinions, debate, discuss car/truck related news etc.
Like I said, I'm not asking for facts, I'm asking for educated opinions.
If you are asking why this thread, it's because I thought it's most appropriate. But if the moderators think there is a more appropriate thread, they can move it there. That's fine with me.
