I have had this hissing sound comming from my engine the last week or so. It really sounds like air leaking out of a hose. I generally only notice it when I am idaling or at low speeds. I setup a time to take it into my dealer but they know I have mods and I just wanted to kinda be prepared or know atleast what I was talking about before they started geting into it.

Could it be the diverter value I installed or something else?

Check your clamps around the DV.

system that the dealer replaced under warranty. Check if your AC works well?
