Hello, Ive recently bought my 2016 sho pp and put on 3k to the car and it’s amazing. I’m looking forward to learning more about the car and from everyone else. Ive also has a hissing noise from the brake vacuum hose, I have already changed out the whole hose line and it’s still making a hissing nose. could this be from the 90° connector on the brake booster?

Is your rear blow off valve seal leaking?

Disconnect and plug the vacuum line at the brake booster. Does it still hiss? if so, it's not the brake booster. If not, you've got a bad brake booster.

Assuming the hissing is at idle, feel along any hoses you can get to and listen for a change in sound.
