Blow off valve?
I don't know much about these trucks. I have exhaust from the manifold downpipe and back with nothing but a small muffler. I have an afe air box/filter. H&S minimax on the mild tune.

While pulling my 34 ft bumper pull with two rigs and a truck camper when I'm pulling a grade and the motor kind of bogs down(like you should've made the trans downshift)? it will build pyro. When it gets up to about 1000 to 1200 degrees when you let off of it there is a noise that sounds like a blow off valve or something...not sure but sound like its coming from the area of the air box.
I didn't own this truck long before i deleted the exhaust and added the airbox and tuner so I don't know if this sound was there before, I never heard it on my all stock F450.
All systems seem to be working properly and its been deleted for 2500 miles.
