"Cuffing" is not normal at all and destructive to the turbo.

Possible causes come to mind ...

* bad sensors like the IMAP, EGR, or Exhaust BP sensor.

* Excess back-pressure on the exhaust system (clogged DOC, DPF, SCR, decomp-tube etc.).

* EGR valve not operating correctly, or EGR circuits/ EGR delta-P tubes clogged.

* CAC leak making the turbo over-spool just to keep up.

* turbo out of calibration.

* Wrong program in engine because someone tried to up the power incorrectly.

==

EGR tune-up, removal of all the cans and inspect their faces, inspect decomp tube for blockage, replace old sensors. That is a good start.
