If there was an over boost condition you would see Code PO234 or PO045! Z

Depends on how long it’s over boosting ..timers have to be exceeded for the codes to be set
OP I forget but is your car stock or tuned when you took it to the dealer?
Sadly I’d be willing to bed that your car has been sitting a lot at the dealer...not that many things can cause over boosting...boost solenoids, wastegates and actuators
With all the limiters and throttle control on the stock tune I’m surprised that it can actually overboost and not throw a complete fit at you....how do you know it’s overboosting?
I am not so sure they 'know' it is over boosting .. i *SHOWED ON A LAPTOP* the boost curve and the s-pattern when it would dump boost when my gate/turbo was bad and see it rebuilt boost it back to 20+psi and they looked like they had no idea what i was talking about. When i said it was the boost pressure in Kpa they didn't have an idea... this was the 'engine guy' ...
My concern is the overheating .. a drop in long block shouldn't over heat, it sounds like the didn't bleed it properly or burp it. or worse they MIXED coolants and now you have jelly in the block.
As to the overboosting, skip the code. Get a handheld from somewhere that can log a 0-70mph run. What i expect is its dumping for another reason. but thats my crazy tin-hat..
