Low and behold, i think people are still forgetting that while this is an M car, it still has an N55.

What does this even mean?
It's a new engine. Different block, pistons, etc. The "N55" designation is just a name, nothing more.
We were half expecting higher power numbers because we thought this car would get a larger turbo vs. the standard N55. Maybe it did, but these numbers look like perhaps it didn't. But given that the main components of the engine are all new, and not standard "N55", it wasn't odd to think the turbo might be upsized too. No one is forgetting anything.
The B58, S55, etc. all put about their crank ratings down at the wheels, very underrated. At least initially, this motor doesn't appear to follow that trend.
No worries, a Pure upgrade will bolt right in I'm sure.
