    Metal cable ties. Takes about 10 mins per side.

    They are fail open. All you have to do is remove the vacuum hoses and plug them.

    It varies with Manettino selection and throttle position. I know the numbers for the 575M and F430, but it is not in the 599 WSM. C1.14 shows how it works and how to service the bypass system, but not its operating range. Here is the F430 schedule, so you can see it varies quite a bit.

    You can assume it opens around 3000 rpm at wide open throttle in Race.

    I seem to recall they opened at around 4000 rpm in Sport mode.
