Turbo hiss

I did some reading before posting this and I think I'm on the right track. I noticed yesterday the truck felt like it wasn't getting full power. Almost like driving with the e-brake on. I did a couple hard runs on the trottle, i was only able to get the boost over 20 psi twice. I popped the hood and checked out the boots on the hot side. They are pretty oily. I noticed when you shut the truck off you can hear air bleeding off from under the turbo. I looked around the firewall and don't see any soot around the y-pipe. I have read where the boots can get a small tear, and show the same symptoms I'm having. I also found where the small hose going to the top of my degas bottle has been resting on the stud on one of the clamps. It has almost worn a hole through it. Gonna replace that also.

Can you guys think of anything else I need to check? Or anything else it could be? I had the A/C worked on yesterday morning. They said they didn't have to take the cac tube off but they were working right next to it. Could have moved it around just enough to tear the boot.

Not personally. I can probably track one down. A buddy of mine is the head diesel tech for one of the big dodge dealers here in town. If you can test it on a dodge I'm sure he has one.

Yeah but dodge piping is 3" and 3.5". You need a 2.5" plug to test with so bring an adapter

check the underside of the boot right off the turbo. feel for it or use a mirror hard to find sometimes. oil on boots is normal.the noise under turbo is most likely from the ac system that you are hearing. there is no pressure in intake system when not running so its not from that.

The veins on the turbo might be sticking? Is there a noticeable difference in a certain power range i.e. lots of low end power but no high end and vice versa?
