Ok, let's get some things straight here
1. There is NO rev limit on the car from the factory. The dealer does not unlock anything in regards to this.
2. At the 1,200 miles service, Launch control is activated and if you have the M package, your top speed is unlocked.
3. No extra power is unlocked at the 1,200 mile point (yes, it is in our heads
). A friend of mine has a dyno and I really wanted to completely prove this - but heck, why
- do note that as engines loosen up, they often make more power - so it stands to reason our cars "feel" faster as we put more miles on them.
And from all my searching I can find NOTHING that says BMW uses a different oil for the factory fill. Someone please prove it - of note, for you young ones on the board, the 1,200 mile service was not originally unique to the M cars - it was all BMWs at one point - because it is a smart thing to do NOT because the oil is different.
