BMS is testing out the electronic wastegate version of the newer ones and has a 2014 435 putting down over 400whp and says there is still room for growth. The curve looks nice and pretty near the top. Color me and my '12 335 jealous.
Let's hope BMW was on to something and the true power curve is exactly what they're painting in their cartoon. The newest development of the N55 makes me optimistic.

incredible that the electronic wastegate has made that much of a difference in tuning potential.....
the m3 is a different ball game as its twin turbos vs single, different internals, different cooling system, different turbo placement etc....
