Lack of power under boost

What would be the symptoms of my turbo dying?
Im tuned cobb stage 3 and I monitored the Boost once and I remember is hitting a peak of 21psi (if memory serves me right).
This weekend went for a bit of a road trip and at one point I floored it and the car made a whole bunch of (induction?/spooling?) noise above 4k and it just DID not move.
When monitoring with cobb the boost does not go over 15psi.
Should I be looking at the turbo or is this symptomatic of something else?
I have a high flow cat installed, do these thing get clogged like stock units?
It feels similar to when my miata cat cell was blocking the exit.
