Stock BOV shot?

[Boosted FC]

Hey guys. What would be some symptoms of the stock BOV going bad? Was driving to work the other day & the rubber hose from the turbo/intercooler pipe going to the BOV cracked & of course the car started to idle erraticly till it shut off. Got her back started & limped her back home a few miles away. I replaced the hose with a new one & tried driving her, but to no avail. The car is tuned to 12lbs & now will hardly hit 9. Also when it hits boost, @ about 4k the car just hits a wall. I am thinking that the BOV is shot and just allowing so much air to be recirced, that it hits the flapper door in the AFM & I guess allows it to run abnormally rich? Mods are full 3" exhaust, K&N intake, FCD, all emissions removed & manual boost controller. She will start right up & hold perfect idle. Thanks.
