Please explain why and what you think is specific to the N54 in the 1M vs the N54 in other applications, that would require a unique tune?

I know the 1M is special, mostly in regards to the chassis and suspension tuning, and of course body work.
In the engine though, there isn't much different that would necessitate a different tune, at least nothing I know of, yet.
I'm no expert on all things 1M.

You say the 1M is smooth and linear, but it's as smooth and linear as a non M N54, stock. Some tunes are better than others in terms of driveability, where piggybacks seem not as smooth and ECU tunes smoother as they control more parameters.

Please explain.
