"Since there are a ton of us out here who have done so, please explain so we may learn!"
Happy to share - here are a few considerations regarding deleting CV
CV is what facilitates 1.2bar 'limp mode' to "SAVE" your engine in the event of fault code. This is your safety net if boost/knock conditions get out of range. If you are not aware, preignition (knock) under boost especially will severely damage combustion chamber components(pistons,valves,head surfaces, etc) in very short order.
simply elimintaing CV without another means of knock protetion IS FOOLISH (to put it nicely)
Even more rediculous is to remove CV,thenincrease boost with MBC - I cannot think of a faster way to cause a meltdown in any turbo car
I personally don't like the MBC aproach for most street cars. Increasing boost in any fashion requires full consideration of engine management changes,increasing fuel needs, carefull tuning and Air/Fuel status checking. If all these aspects are not carefully accounted for you are asking for BIG TROUBLE

usually after they collapse it gets harder to pull the head with the headers on.

You have a signal massanger or anyway to adjust your a/f ratio. You will need a WB to monitor your a/f ratio as well.
Otherwise removing the CV valve and increasing your boost level with a mbc is plain "dumb".
