Guys,I dont believe that it produces more power just a quicker throttle response - I drive My M in M dynamic mode with power key activated from time to time to make the pedal feel lighter.Similar feeling with most "sport" buttons.Not for power gain because its too cheap............you know what,Im quite tired of that electronic feel when I release the clutch,give me some old fashioned cables to operate.The newer cars feel like theres an on/off switch for everything.
