6.0 - No power high rpm/no smoke or CELs

Alright. I got the truck a couple days ago. I realized I had no power up high (above 2k). Popped the hood yesterday and my buddy pointed out the last owner tried to duct tape the coupler onto the turbo and used hose clamps on the other side of it instead of t clamps. I clamped the couple back on thinking that might have been why it had no power but still nothing. The truck runs fine below 2k but I dont hear the turbo spooling up at all. I pulled the intake off and it spins freely and doesnt seem to have any shaft play. I then pulled the charge piping off the intake manifold and I can feel it blowing and hear it whistling through the pipe. I have no CEL and took it to autozone and had them scan it anyway with no codes. It also isnt blowing out any smoke out the exhaust at all. I just unplugged the batteries to reset everything hoping for some stupid reason it was in limp mode but still nothing. Im gonna pull the egr and check the FICM tomorrow. Any other suggestions?

What is the EBP and Boost pressure? Sounds like boost leaks. Maybe you have an up-pipe exhaust leak, do you hear anything? Fix that with new boots (if needed) and clamps, get a suitable monitor and report back.

What twoicebergs suggested is very a good start. On my dads truck we had the same problem you are describing, I cant really remember what the remedy was though. When you go over 2k RPM does the truck just fall on its face or does it just lack on power? While you are in there, check that all the connections to your alternator and FICM are on there good and check your exhaust back pressure valve. but first do what twoicebergs suggested.
