Hello, I've seen all the videos, but I haven't heard the sound from my blow-off valve.
Green 2psi spring.There is a fluttering sound like a small bird chirping.
I don't know what the problem is. Help me. Max boost is about 12.5 psi, and you can hear it on Excel-off every section.
bov vacuum hose was connected to the stillen manifold and connected to the boost gauge using T.
I don't know if the installation is wrong or if it's a component problem. It was installed for the first time a year ago, and I heard this sound from then on.
