If I install a TurboXS 4.5bar MAP sensor in place of the stock MAP sensor, can the MAP sensor voltage values be recalibrated with an ECUtek reflash?

i.e. stock map sensor, 5V = ~22psi. With the new TXS map sensor, 5V = 4.5 bar (~50psi).

BTW, this is a 04 STi.

you can for sure recalibrate it in the stock ECU. I am not sure whether ECUtek exposes the variables but I presume it does.

yes, i can be rescaled using maps that have been available to ecutek dealers for over a year now.
