Hmm.. I hear you and agree but I find it hard to believe that a mild cam/compression tweak on the new motor couldn't produce a reliable 280-290HP.
Tuners will find this hard because of the valvetronic/VANOS/ECM but BMW engineers could probably do it during their lunchtime game of Minesweeper.
A set of cams and an ECM reflash for say $1000? Who's in?
