Those aren't the dyno graphs of the 2014+ N55s. The early non-EWG N55s have smaller turbos. Although BMW kept the power rating the same, there's a difference in stock power and the shape of the curve between the pre-2014 and 2014+ N55s. The EWG N55s can make 390-400whp/400-420wtq on 93 whereas the non-EWG variants are limited to around 360whp/380wtq plus they lose power above 5600rpms.

Tunes simply elevate the curve and power still tends to peak between 6000-6200rpm.
