I settled on the RK tunes. Going in a week or two. They do it in house, have results, and are able to modify their own tune whereas some of the other tunes are immutable and the results are a mystery or fall short of what is advertised. The Carbahn tune is shady simply due to them advertising a tune that applies to 2 different Motors. A 2018 m550 is not the same as a 19 or 20 m850i or the 2020 m550i. Something in their marketing doesn't add up and it doesn't seem wise to take a chance on their tune.
