I believe its' when carbon builds up from lack of true heavy use. Every once and a while you have to really punch it and let it get up there boost wise to burn off the buildup that gunks these turbos up.

Take it to your dealer, they will try to clean the turbo or replace it with a new one. This is a somewhat common problem on the 6.0L trucks, and is normally seen in trucks that don't get driven often, or get driven on a lot of short trips.
Do you have an aftermarket air intake? Some of those have also been accused of increasing the problem.
The turbo is covered under the 5 year 100,000 mile emissions warranty with no deductible, don't let the dealer try to convince you otherwise.
