Hi, had my F10 M5 (stock except for drop in BMC filters) on the SRSpeedworx dyno today as I was fetching a JB Stage 1 for this car. Measured 414KW and 796Nm on the wheels on the second pull (other pulls were similar). Coming from a modded 2015 M135i I was quite impressed with these figures. These engines are brutal! JB Stage 1 should add about another 25wKW and 40wNm on that? What are the experiences of other F10 M5 owners - stock and modified? Cheers Peter
