Annoying vibrating noise when acceleration over 3000.

There is an annoying vibration sound coming from the passenger side window. It appears once the engine is warmed and the acceleration is over 3000rpm. It becomes less noticeable over 4000rpm probable because the normal engine sound is louder. The dealer has wrapped heat exchangers which may have helped temporarily. The mechanic seemed to think that it was related to the turbos kicking in. Any help would be appreciated.
