Your reasoning is very sound, except for one detail - Stage 1 (and OTS tunes in general) can be dangerous. If it is safety you are after, you should get it tuned by a tuner, utilizing wideband 02 and perhaps even EGT sensors.

I suspect that the TMIC with an OTS stage 1 map could possibly throw something off by enough to either cause damage or unwanted behavior. Less pressure drop also means higher than expected boost, or boost sooner than expected.
