That was the post that got me thinking about all this. My point is you don't have to do that. The controller is controlling to absolute pressure. If you set your boost to 20 psi and your boost adder to 14.7 psia, the controller is controlling to 34.7 psia. If the ambient pressure is 10.7 psia, the controller will control to 24 lbs of boost, but this is fine because its the 34.7 psia that matters to the motor. In this case, 24 lbs of boost is not overboost.
I think the boost correction works to the psia value, not the psig value.
