    Hey Fellas,

    When I am in sport mode, I get a really loud hissing noise upon acceleration. Is this normal? If not has anyone else encountered this? Thanks in advance.

    Difficult to ask where it is coming from.... What kind of hissing noise is it? Does it remain steady during acceleration or does it oscillate?

    Basically it sounds like a blow off valve from a turbo or s/c.....as I accelerate it remains steady, no oscillation...looks like it's going in to the dealer. Thanks fellas.

    Maybe your car was secretly turbocharged at the factory? On a more serious note, maybe a hose or a compression fitting has come loose causing the sound.
