whistling noise

[info]

SO the best way I can describe the noise is when I let off the gas and the engine brake engages, I get at the same time a sucking and whistling noise. I have no loss of power no codes come up.

Some info about your truck would help, trim, year, engine, etc.

Do you you have a turbo? What you describe without knowing what you have sounds like a turbo whistle.
