    So the B58 has no BOV/DV and uses a combination of things to avoid this:
    This makes me wonder how this balancing act can be maintained after moderate to heavy modification. Combined with the no/little vacuum aspect of the Valvetronic and electronic wastegates, it seems there is a little bit of engine tech to catch up on.

    If I recall, the EWG was done midway through the N55, it looks like the N54 will be the last engine with these functions.
