Hmm... a direct answer to your question is "I'm not sure". I don't see any MAP scale table in anything I've got.
An indirect answer is that it doesn't matter. The MAP sensor signal to the ECU is capped by your UTEC to whatever voltage corresponds to 12psi on a stock MAP sensor, plus the factory ECU doesn't use MAP for anything except for boost control (which you're not using) and a brief moment after a (cold?) start.
