I don't have the answer to your question, but I was wondering why are you switching from the 6765? Any problems with it? Too laggy? I'm asking because I'm considering the 6766.

You can bolt two GT55īs on the side of the block, and it still wonīt produce gazillion HP at 14.7 PSI
You can enhance volumetric efficiency and through this power at same "boost" by more efficient compressor and bigger turbine or also by more aggressive porting, custom intake manifold, revving engine to the stratosphere, having no exhaust at all etc... But you can do only so much before gains diminish and all these mods cost big money without much gain and canīt be used in road going car. And since 6765 isnīt restriction at your level, there is no other way for more power than increase in boost, since boost isnīt cause but consequence of flow. Also, everytime you go up in the size of turbocharger without using it as it was intended, youīll just make your car more sluggish...
