Lower performance after dealer service?

I've seen a few messages online about a new software update for the F30 that lowers its performance ahead of the introduction of the new M Performance parts, which apparently include a software tune. This is allegedly done to better separate stock cars from M Performance "enhanced" cars. The owners reporting this went in for service and when the car came back dealer said he applied mandatory software updates from BMW. Apparently one of the things these updates do is lower the output of the engine. Output is still above the rated 300 but less so than before.

Dealers are not necessarily aware of it since they don't know 100% what's in the software updates. Only BMW knows.

Unfortunately I couldn't find the messages again, I believe I saw it on F30post and Bimmerfest.
