    Hey !
    looking to see if anyone has some ideas.
    2012 Pete
    new turbo, new head, new pistons, new liners, new air to air, all in the last 2 weeks.
    Has the whistle on the driver side, not when idling !
    Now check engine is kicking on when under load and higher RPM'S. stays on for about 30 seconds then off .
    attached a video !

    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?
