does it stop every time at the same rpm? if it does, CAS is bad/going bad and is in limp mode. Does it only happen under boost conditions? then its missfiring so, coil packs, spark plugs, fuel. fairly simple.

stock turbo?
i deleted my bov, it ran like jesus...my leaking bov netted me about 6-10 mpg
after i deleted it, i got about 27 mpg. not great for your turbo, but ehh

I also had the same issue when i was using a carter replacement fuel pump....drove fine until about 3k in boost, then it would lean out badddddd



ps: i asked if its stock turbo, just because i wouldnt run comp surge on a nice expensive turbo

check vacuume (sp?) lines to fuel regulator. if you have access to a halfway decent obd scanner, look at live data. It will give you a value for your maf. see what it does. also while looking at live data make sure all the other numbers look correct, like coolant temp and all that good stuff.
