Basically those diesels are competing with europeans.

Boost is unbeliavable. but after env temp rises to 25 C there no boost, IC sucks?

At +3 temp car is rocket.

My M6 has 36 tkms, I chipped it immediatly because my M3 2013 suffered exhaust cam problems and M6 w auto gearbox was only alternative 2018.

My 2017 M6 150 HP automagic is very good car to drive with 192 HP tune. I personally hate automagical gearboxes, but M6 is a way better car with tuning software. Acceleration is unbeliavable, 1600 kg piece of iron takes 7 sec 0-62.
