I've noticed a slight hissing noise from mine, but I've got aftermarket intake and exhaust. The hissing on mine starts at a much lower RPM, but I haven't noticed any symptoms or engine codes that indicate an engine/trans issue. I'm guessing I have a very slight exhaust leak, but I still haven't climbed under there to check.

I would check the flap inside the intake manifold that
opens when you hit 4000 rpm.
opens when you hit 4000 rpm.
