If you have a 20psi map and 10psi map surely the car will produce 10psi at the same rpm?
More or less, the 20psi target would probably mean you made 10psi a little sooner as the waste gate would be fully closed. If you target is 10psi the waste gate will begin to open before 10psi to avoid overshoot.
