Default Engine noise at 55

I have noticed a whistling sound coming from the engine (HEMI single exhaust) around 55 MPH. It occurs when climbing hills and adding just enough gas pedal pressure to maintain speed. If you push the pedal harder or let off of it goes away. The dealer said they didn't hear anything unusual. Anyone else ever heard it?

Sounds kinda like a forced induction? Like a supercharger but quieter? I hear it all the time, but only when accelerating. I like it and the dealer said it is completely normal.

I haven't heard that. I have driven at 55 mph too.

I wonder what it is.

My Dak did something like that. Never did figure that out, knew it wasn't a bad thing though.
