Loud hissing and no boost

I have an 05 6.0 powerstroke and recently I started to get a loud hissing and no boost untill I drove it for a few minutes and then the hissing would go away and it would start building boost again....now it does it everytime I try to drive it whether its cold or has been running and warm..plugged my sct in and checked for codes..it showed P0069, P0113, P0470, P0528...

You have an air leak somewhere in the charge air side, could be a hot side rubber boot, cracked intercooler, or loose clamp somewhere. It would explain all those codes except the fan speed sensor code(P0528). For that, check the connector on your fan shroud for condition and proper installation.

Check the rubber boot (the one with a slight bend in it) going from the turbo to the hot side pipe. It tends to flex and split over the years. If its coated in oil, it's probably history.

There is only one way to inspect those boots and that is to remove them. Of course they will "look good" because what you see is not where they fail. They fail on the underside. If the boot has dirt stuck to it, it is suspect. The reason why is that the CCV is connected to the air inlet tube just prior to the turbo (introducing oil vapors to air inlet). That boot is made of silicone, and silicone breaks down in the presence of oil. The oil will make the boot porous and push its way through the boot. That dirt you see on the outside of the boot is actually oil that has made its way through the boot and road grime sticks to the oil.
If the boots are dirty on the outside, it is best to replace them.

To check for exhaust problem, have a friend stick his foot over the exhaust pipe. If it is exhaust related, you will hear it that way. If the noise comes from under the hood, lay down under the truck while your pal has his foot over the exhaust. Using a long stick with a thin strip of paper taped to the end of it, move the stick around the up-pipes (especially the flex joints). Also check the firewall for soot stains.

If you, or someone else, has removed the turbo recently, suspect that they Y-pipe is not properly seated into the turbo inlet flange.

NYC is right, the flex pipes do have a tendency to crack over time.(bout 165.00 at ford)I had the same noise a while back and the clamp to the downpipe wasnt tight enough so I tightened her up and it was all good.
