2018 6.7 Fluttering noise with throttle?

I have a 2018 and since new under acceleration you can hear a faint fluttering noise that gets more noticeable as you give it more throttle. Figured it was a normal sound but after a while it started to get annoying and i second guessed myself.

Took it to the dealer and they told me they don't know what it is but think its normal.

Anyone else notice this?
Its most noticeable when at highway speed on cruise control and music and heat must be turned off to really notice it.

I hear it in my 2017. It sounds like a cross between something loose under the hood flapping in the breeze at the same frequency as the engine and water spitting out of a compressor pop-off valve. Drives me nuts sometimes.

My '18 does this but only on decel. If you find a road that's level and coast between 32mph down to 25mph, it will flutter away.
