Do a boost leak test and give us an update.

with an broken xbc extreme mbc

Replace the mbc? After checking for a boost leak of course.

Boost leak or wastegate arm came off the flapper.

I haven't done a boost leak but when I do gget into boost it tend to stop and struggle around 5 to 7 psi. Couple days ago ill go up to 16 beautifully and 19 before the mbc broke.
I don't have the proper tool to do a boost leak...anyone have time to do it for me?...ill drive to your place with a pack of boozesss if that's needed to. Thanks guys.

So the MBC broke but your not sure why you are only getting 5 to 7psi? The car will feel like its struggling if it went from 16psi down to 5.

I second that. You can get everything you need for one at Home Depot.

Got it fix. Took work off to fix the car and found major boost leak coming from the exhaust manifold. Boost turned up to 20lbs now and it feels good.
