Bottom line is Instead if locking down the Boost Psi, as all the other methods do, Porsche targets the same power at sea level vs my 3500ft DA by varying the boost based on the DME calculating Real Time DA.

I don't understand the technicalities of what you're talking about, but what you're describing is why BMW no longer has MAF sensors on the F90 intake tract? Is the change to electronic control of the turbo waste gates instead of vacuum also part of the predictive tuning?
