yes

no idea why use a bigger maf housing, but linearization i would drive out the old way.

open loop, testing and gettin closer and closer..

F21's are a lot more than that - you'll want to be running less boost than that if you're going to run that turbo for any length of time - keeping it to a bar or less of boost tended to get us 5-10k miles or about a few weeks @1.3-1.4bar on all these various cheaper billet ones we tried.
Not sure of any benefit of the compressor wheel save for weight if there's no info on reprofiling and extended tip air flow testing - therefore I'd probably get a billet wheel on it's own (I used to deal in bulk so they were about £30-35 each for me but you'll be looking at prob £70-140 for one currency and supplier dep). OEM Borg-Warner re-build kit - check fitment for any light porting/chamfering work when adding the wheel and have a local company balance it all. Prob about same price plus you keep gen BW parts - just my 2p.

You prob want to sort the tune out better too, those are low figures for your mods & boost - my base map @15psi got those figures on a stock AUQ with induction with very mild changes, 230ps/356nm @ 1.1bar, very little to no ig ret even after spirited driving etc
