The N55 definately sounds better than the N54. In the real world, they are pretty much equal in terms of performance, but you hear a nice turbo spool with the N55!
Funny you said that. I hear a better distinguished turbo spool on my 07 335i than my 135i /N55 equiped car. maybe It's still being broken in. mine only has 500 miles on it.
