Congrats. Mine has been a daily driver since new so I've only very mildly tuned it. We didn't get the FQs so we were always somewhat jealous. The Audi has taken over daily duties so I'm contemplating what to do with the Evo. Don't think I'll ever sell it since I don't care for the X - if I want an Audi, I'll buy an Audi, not an X (see photo above).
We didn't get AYC/S-AYC here so we don't have the pump, lines, insane service interval, etc. IIRC, Mitsu claimed it was so they could give us a bigger fuel tank although I suspect it was so they wouldn't have to warranty the things when we failed to service them.
