I have a brand new t trim head unit installed, everything is great except I'm getting crazy flutter from the blow off valve. Even under very light acceleration. I opened it up as much as I could and it helped, but didn't fix the constant fluttering. I have the car at a performance shop doing some other work, I asked them to put a bigger blow off valve on to fix the fluttering. He said when they took the existing blow off valve off, It was still making the fluttering sound. They put a 52 mm bov on with the same fluttering.
Has anyone come across this issue?
