Question on Launch Control: I saw a BMW video where you can adjust the RPM while the checkered flag is on using the Cruise Control adjuster (up/down). The recommendation is 3000-3500 RPM.
Does this work on the m550's or just the M cars? If it does work, did anyone get better 0-60 times by doing this?
EDIT: It's the first video at 0:40 :
