If I take my TDI as an example, I agree that at cruising speed on a flat road the turbo does not produce enough boost for the wastegate to open.

In this case a better option might be a 2nd turbo dedicated as a compressed air source.

Donee, the "electrical bleed" that some people do to the VGT 4th gen TDI turbo will only up the boost limit. I'm pretty sure the turbo is shooting for as high as it can for any given operating state below the limit.
