Angry 1997 7.3 OBS

Hey guys. I just needed a bit of knowledge. The other day I was going down the road when my truck lost 90% of power and was missing like crazy. It would idle with a light gray-blue smoke bellowing. My automatic thought was a fuel related or timing issue. I replaced the CPS and Lift Pump with still no luck. I can turn the vehicle over for about 5-7 seconds and it will fire up and idle with a HUGE miss. Injector buzz test said injectors passed. When I was disassembling for the lift pump, I noticed a plunger on the exhaust side of the turbo was pulled almost out and angled in the direction of the driver side of the vehicle. I pulled the exhaust loose from the turbo and felt inside of the turbo. I thought there was a butterfly attached to that plunger. If there is supposed to be one there it is now gone. Any response or help on the matter would be GREATLY appreciated. Its my only vehicle so I'm kinda in a bad spot. Thank you so much
