Question Help, whistle no power

Have a 04 F-350 Driving on the interstate this morning, started hearing a hiss comming from the exhaust (sounds like that locations, hard when going 65 down the road). Released pedal, dies out with boost, comes back with boost. Low on the power now. I'm thinking turbo, any other ideas out there? Any and all help would be great.

Don't really understand what this means....

Try to pull codes, would be a great help for us. Without it, I'd check the boost pipe boots.

I feel a little silly, well after much looking and a lot of digging, turns out my pyro sensor came out. That caused all the hissing when I was stepping on it. Thanks for the help.

I had a simular thing happen on my truck while towing my camper this fall. My problem ending out being a torn intercooler boot on the turbo connection. I had a noise and could not find it untill it finnaly ripped all the way and the power went down ant the pyro went up.
