So here is a variable in the whole break in service give performance boost for what ever reason.
There are a number of forum posts since the update to 2022.7 was released where people, including myself, swear about differences in sound and shift behavior in various drive modes. I can see a situation now where someone goes in for break in, gets the update, and equates the break in service with the unlocking of more power from BMW. Just throwing it out there on a 20 month old thread.
