2013 EB strange moans under hood while acelerating
 

My EB makes a moaning noise when I am accelerating up to speed when driving "old Man " style. I guess its the turbo blow off valve(s) like used to happen on my old 7.3's. I hope its not anything to worry about. The truck runs string and gets 18 mpg mixed driving. I do get bon it a lot too. Any ideas?

Might be trans noise

I sometimes have a strange noise in my passenger seat while accelerating my 2011 ecoboost.

I haven't yet grown the marbles to tell her to just shut up! }>:-drink

There is no blow-off valve in a 7.3L. It's a diesel, so no butterfly in there requiring a BoV...
