That's actually an increase of 165HP (AWP) at the wheels! So if I sold it to a desk ship and they turned it around to sell it they would advertise it as a 2019 BMW " " tuned with 621HP!
I have videos and pics of dyno test, in car videos of 0-60mph runs with Dragy analyzer and some burnout doughnuts if anyone is interested.

Doesn't work that way. You need before and after Dyno's to compare deltas. Although I'm sure BMW rated this engine at 450whp which is still an impressive 100whp+ gain.
