Still in the honeymoon period with my new Lightning Blue MCS (only 250 miles on the odo). Best car I've ever owned, hands down.

Anywho, I was wondering how much I should expect the car to "loosen up" in regards to acceleration....I know it can take a few thousand miles for engines to get up to their full potential.

Not that I'm complaining, of course...my R56 is already much quicker than my RSX-S that I used as a trade-in....

 

Don't know about the turbo motor, but my 2004 MCS really began to come on strong after about 20,000 to 25,000 miles on the clock. I found this to be true of my 328i as well.

Just observe your run-in period and then, if the new motors wear-in like the Tritecs, enjoy the engine as it steadily gets better and better!

Sounds about right, just make sure to follow proper breakin procedure. I don't know about R56 motors but improperly broken-in turbos are notorious for being down on power vs properly cared-for examples, burning oil, etc.
