Also considering underrated S63TU, I expect 600-620 HP and 540-570 TQ at Crank for stock M5/M6 (non CP)

Certainly don't mean to rain on your parade sir, because I am in it -
Heard this before but rumor has it that Lieberman and God knows I don't care for him, but he did dyno live M5 vs E63 AMG and M5 was right at 550HP and 500 tq while AMG was the one that was really underrated! !
Please correct me if I'm wrong !!
