Alright guys need a little help........

I've got a screeching problem that still hasn't been resolved yet. I've taken it in once and they said they found a leaky divert hose and they replaced it. The screech was still there but I wasn't losing boost anymore. The screech is getting bad and now everytime it happens my boost falls considerably. The screech usually starts at around 15 psi it will then make the boost fall to 10 or 5 psi. My car boosts high as hell sometimes reaching as much as 28-30 psi. I also have been noticing that there is some hesitation in the rev band when in 3rd,4th, or 5th. For what its worth the screech sounds like a pig that is getting the crap beat out of it.
Any thoughts?

It could be the DV. The stock is a diaphram type and will...>>

cause sounds like that. Does the boost leave around 3000 to 3500?

Just a thought.

I've changed 4 dv's all together so far.

including a Forge DVR. I thought stock dv's were piston type?
what do you mean by leave at 3k to 3.5k

Usually a bad DV will start to loose boost around 3000 to 3500 rpms.

oh, No it holds when its anywhere from 5-15 psi

at all rpm's. But anything above that it starts screeching and it will kick the boost down.
