Great looking 1, and enjoy your n54 engine. I know I do and my car weights a ton more.
I would not count on that being "undetectable". The new Ford 5.0's had people claiming the same until warranties started getting denied for tunes.

Ford's method involves a key cycles counter, so even if you have the stock file loaded, the numbers wont match up, E.G., 20,000 miles but only 10 key cycles....

I'm sure BMW is just as, and most likely more sophisticated than the Ford ECU.
