Check all the turbo boots. One may have come off. Also check the intercooler inlet. I've seen it blow off before. Passenger side by the radiator. If you still hear the turbo spooling I think you're ok. You just have a leak somewhere.

Also, if the egr valve failed, or the o ring on it is bad, you won't have any power.

im not to 6.0 savy,i mostly work on heavy equipment ,where is the egr located at, the valve it self i mean........i got a 7.3 but i know these are a different monster

It's to the left of the fuel filter housing. Has a wire harness going into the top of it. Probably a 2" diameter. I've had those o rings go out in me before.

I'm not an expert, or even close. Maybe some of the more knowledgable people will chime in soon with ideas.

I'm awake and happy to help! lol.. it sounds like intercooler boots.. but try taking the turbo apart and cleaning the veins as well.. they have a tendency to get clogged over time..

for the EGR you may need to get a pry bar under one of the ears to pull it out cause its in there tight
EGR location:


or here.. what the metal things are holding:


and this is the passanger side IC boot.. just remove that bottle if you have an F-series.. and it looks just like that.. its where the pipes come up for the A/C system:
