so port the head if you want more flow.
I don't think anyone is picking up on what I'm putting down here.
Run PI with 1000cc Bosch style injectors as your main form of fuel.
Run your DI as the lower volume supplement much like we do now with PI supplementing DI.
Basically backward of what anyone is running.
I actually like this idea, but its more of a tuning subject rather than what is going on here.
A ported N54 head will flow what? Compared to the N52/S54 head? Price of super aggressive port job vs a used 328i head?
