Before 4000 miles, when driving and getting on it hard, at about 4000rpm the power just seemed to trail off and go flat (after a good run in of course). Now after 4000 miles, that trail off seems to have vanished. Does anyone know if there is some kind of auto-restrictor until the car gets some number of miles on it? I know that this is being done on several motorcycles and cars... Thanks for any input, my BMW dearler didn't have a clue....
