However, in the last week it seems like I have signifincantly reduced power in lower gears for the first few minutes of driving every morning....almost feels like really bad turbo lag I used to occasionally get with my 335i.
Does that fit with an impending injector issue? Of note, I did use a bottle of Techron fuel additive this past fill-up, so I was curious if that plays into the less than optimal running of the engine for the first few minutes.
Sorry for the " FNG questions"....just starting to get into BMWs/cars in general.

Sounds like my experience. Just had to keep on the dealer for getting deep into what could be wrong. Fixed mine and no soot and getting more power and better has mileage.
