Re: How do you know if your stock DV fails? (macroz2)

DV will make fluttering sounds when letting off the gas. My car held boost fine with a busted stock DV, but it wasn't opening between shifts. That fluttering noise was the air not being able to escape so it rammed back into the turbo, nice huh?
You can take the DV off and push up on the piston and put your finger over the vacuum hole, if it stays up then it's good, if it falls then it needs replacing.
