Oh - and with the E60 some folks reported a gain of 20HP. I'm definitely not claiming that
I always believed that it was a 1.5hp gain on the E60 M5 with the charcoals removed, but this included a slightly better engine response. Who knows!
With the E60, it seemed to me that when you went from a 550i to an M5, while the leather and the sat-nav were the same, underneath, it was a completely different mechanical driving platform. With the M550i and F90 M5, that vast difference isn't really there.
