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!
The E60 M5 was the Porsche GT3 of M5's, while the F90 M5 is the Porsche Turbo S of M5's, and the F10 M5 is the Porsche GT2RS of M5's.
