    Speed limiter set to circa 100mph.

    You'll still get a ticket however nonchalantly you whistle at that speed. ;)

    The police car behind you maybe?

    Seriously is this a definite engine noise as opposed to air passing a trim part out of true.

    I had this on a Toyota Avensis which sounded like engine noise but was cured by adjusting the rear door.

    At low speeds I don't lose power and the car will rev over 3000 if I drive over 70-80 etc for a while then it slips into like a safe mode agai n and won't rev over 3000
