I suspect air intake hose popped off

I had a similar situation when I had a dodgy BPC so I was driving around with the wastegate hose deliberately disconnected from the BPC (the middle hose on the BPC). Naturally, you have to be careful when driving like that as can easily overboost and hit full cutoff which is scary and the engine will not thank you if this happens repeatedly.
Anyway, I went to overtake a lorry on a hill on the motorway(freeway) and I almost instantly hit the full cutoff but suddenly the car now felt like a 2.0 non turbo. No horrible noises, just gutless, could barely maintain 70mph.
At the next service stop I checked under the hood and everything seemed fine, until I noticed the air intake tube had popped right off the throttle tube.
It could be a different bit of tubing in your case, but it sounds like something between the turbo and the throttle tube to me.
In summary, I think your BPC fell off, caused the wastegate hose to disconnect, which caused a massive boost, which popped off your intake hose.
Good luck!
