False. You can use LC (as someone already mentioned) it is not disabled and unlocked @ 1200. The manual says do NOT use LC during break in.

As for the additional power myth please see the video below from Classic BMW where the M3 gains 28hp after the 1200 mile service . It dynos 301.6 to the wheels before and 329.6 after. The amount of power gained may vary among all the different M engines but it's certainly not a myth.



Wrong see video below.

M3 1200 mile service before/after video:





Those of you quoting 4000rpm must be talking about a different engine or M car.
Page 300 in the M8 manual (and page 274 of the M5) states:

"Drive at varying engine and road speeds, but do
not exceed 5,500 rpm and 106 mph/170 km/h.
Avoid full load or kickdown under all circumstances"
Glad to hear about the LC but for the extra power I see no proof related to modern M-cars. Our M8 certainly felt the same before/after...

A F90/F92 pre/post 1200 mile service dyno would be more relevant to me than mentioning what's in the manual
