Drove an E92 M3 with 156km(still new) and it felt really flat.
Jusat need to know if they are detuned till 2000km?

Hmm.. interesting. Very possible. The RS4 is detuned and has two bumps in power, one at about 1.5k and the other about 7k-10k miles that we have been able to confirm. Maybe a similar arrangment exists in the M3.

Picked my car up today and dealer said that the car is set-up not to be at full power until the 1200 mile check...when all fluids are changed...brakes are seated....clutch etc. are all broken in properly.
Take it for what its worth:dunno:

All they do at the running in service is change the oil. The fact that power is electronically limited prior to the running in service is an urban myth. The engines are very tight for the first 5k miles though and are much more responsive once they've loosened up a bit - especially if they are run in properly. Far too few owners read the running in instructions properly and floor it after the 1250 service. It takes 3,000 miles to run in an M engine and the idea is to build the revs and top speed GRADUALLY between 1250 and 3000 miles.

The only time the car is limited is when it is in "transit mode" between the factory and the dealer - it has electronic restrictions and suspension blocks in place to protect the springs and shocks and has a very low limited speed to stop the guys taking them off the boat and transporters at high speed and ruining the suspension!
