Now as for your "overtaking M5 by several cars" i find that hard to believe unless M5 driver was sleeping. Fastest M550 (2020-2021) for 100-200kmh on dragy is 6.59s which is still in M5 stock territory, not to mention it was by set by someone using BM3 tune. Post your 100-200kmh run or 60-130Mph, lets see those magical numbers you're talking about.

99% of m5 comps are not running faster then 7.5 60-130 stock of course
