Ah, gotcha. The difference is the 3-stage intake and corresponding retune. You can actually buy it pretty easily from vendors. As I mentioned earlier the N51 already has that intake, but needs it just to get back to 230HP because of a lower compression ratio. It's still fun to feel it pull through the revs, but admittedly not as much fun as it was in the Z4.
