Egr Question?

How can you tell if your Egr valve spring is week and blowing open underboost? No boost gauge, No codes, But truck is way down on power and doesnt build boost like it once did.

Any hissing noise? did a CAC boot come off or have a tear or slice in it?

Take the EGR valve out and see if its stuck open.
