General AP question regarding larger turbo

[AutoEuphoria]

I was thinking about this the other day...what changes would be made in ATR to accommodate a larger (or different than stock) turbo running an external wastegate? The boost tables would become obsolete, wouldn't they? Because the stock boost control solenoid and wastegate would be taken out of the equation? Other than that, what would be different?

Now, if I ever went this route I'd definitely get a professional tune, but what would someone do to make a tune that would be "driveable" to get to the shop (without getting into the boost)?

IDK about the ATR stuff but you could drive out of boost to the shop on the stock tune just fine
