Check and see if CAC hose clamps are tight. Possible turbo boost leak. Also can have the shop scan engine for codes, that way you know exactly was is going on..

Air compressor intake hose is on the driver side? Often overlooked boost leak area.
Has this been there since repairs were made or something new? -
