So I finally have the 18T turbo and am ready to re-program my MSII. Lots of
opinions on which setup to use and all the arguments sound reasonable. Any real world experience or links would be much appreciated. M110, basically stock D-Jet engine with EDIS. Thanks.

Use MAP. I do. Works good. Mafs can be laggy and difficult to tune, esp with lengthy intake tracts. Alpha N won't account for boost well.
