I think it might be more along the lines of not having the technical know-how rather than lacking the desire. The N54 is more of a 'traditional' turbo six in that it uses two tiny turbos much like the B5 S4. To go faster, simply upsize the turbos slightly and trade some lag for much more flow. With this dual scroll thing it is infinitely more complicated. I don't even know of any other production 6 cylinder with a single dual scroll turbo as a point of reference. I know the outgoing 911 Turbo used a couple of adjustable vane turbos. Anybody know of one?
The Porsche VTG is much different from our turbo! You can't compare them!

I read a lot of threads were it was discussed that the difficulty in tuning our N55 is integration of the Valvetronic and the new DME's... The hardware isn't the problem to upgrade i think ...
