Unlike most manufacturers, BMW actually put some effort into keeping the performance specs in line with the non-SULEV ones. I think the primary difference is an intake manifold carried over from the 330 engine. (There is a thread somewhere detailing this.) The only weird thing I can say about mine is that power to 3K RPM sometimes builds linearly and other times it feels like nothing followed by a sudden surge at 3K. I can't say if that's a SULEV-specific issue or not, since I have nothing to compare it to.
