Bmw put the n54 in the 1m for a reason, its a collectors car and they wanted to give them the more powerfull and more tunable engine.
Now whether the m3 uses a worked n54 or n55, it doesnt matter, its a reworked engine, not stock so it doesnt mean anything.

You know you are 100% correct. Those BMW engineers are sneaky. Do you know how many hours they must have sat in meetings talking about how they can screw the tuning world? That they wanted to make the N55 to "screw" people so they do not modify cars? Yup thats the reason they built it! lol
This is how it went.
"Well lets design this chargepipe to hold 8-10#s of pressure. Once they go above that BOOM the pipe will break! That will stop those guys from tuning our cars!!" HAHAHA!! That is some of the most ridiculous speculation I have ever heard on a forum.
FYI Been running 15-16psi since the car was new and now has 24k on it, I havent popped a chargepipe yet.........
