If you tap the brake pedal does the "hissing" sound go away? If it does then it is just the EBPV closing and the truck idling up a bit to warm it up quicker

Had my ebpv unhooked for about 3 years but I hooked it back up so she could warm up a little quicker - it's been a cold winter this year. With the 4" exhaust & a fairly loud muffler, I call this my jet turbine - I think you can hear it a quarter mile away. And mine also makes some noise around the turbo area but I think that's normal.
You can unplug it & see if your problem clears up. Should default to always open when unplugged.

The EBPV is designed to disengage when you hit the brakes. In stock form, Ford did this to prevent it from being an exhaust brake. If you hit the brake and the hissing does not stop, then the EBPV is sticking.
If you are having trouble accelerating, then the exhaust backpressure sensor tube might be clogged. If this gets clogged, the EBPV will delay opening or not open at all when accelerating. Here is a link showing you how to clean it out:
Welcome to guzzle's Exhaust Backpressure Sensor Cleaning Maintenance Web Page
Or if you don't want the EBPV, you can disable it. Under the turbo at the pedestal, there is an electrical connector. That hooks up to the actuator that controls the rod that opens or closes the EBPV. If you unplug that electrical connector, it disables the EBPV and prevents it from closing.
As for the wastegate... you cannot hear it open, it's impossible. So the noise is not wastegate related. However, if you have a code for the wastegate, delete it and see if it comes back. If not, then don't worry about it. If it does, then you have a problem with the solenoid (sits on the front of the intake spider), or a problem with the wiring leading up to the solenoid.

Any wastegate code is related to the solenoid or wiring only. It will have nothing to do with the wastegate itself, or the actuator.
