Yeah， At higher RMP, the noise becomes shrill, resembles whistling sound in the mix of engine sound , but very subtle , one needs to roll down the window to hear it, on the left side. May be I am being paranoid and over sensitive, but the noise is there, for sure!
I am going to the dealership to let the expert to listen to the noise. Small Air leak can reduce power of the engine slightly.
