Post 2015 3.5 L EcoBoost Noise

Good morning guys! I have a question that I am hoping someone can answer. My 2015 F-150 with the 3.5L EcoBoost has about 16,000 miles on it. Recently I noticed that when I let my foot off of the gas, there is a sound similar to air releasing that comes from the front end.

I assume that this is the turbo un-spooling, but I am not certain. Has anyone else experienced this? Is this anything to worry about?

Thank you guys in advance!

BOV ( blow-off valve )

Check to see if it's still got the tubing fully connected at both ends - at the BOV itself and the left intake pipe.
