Glad it was helpful. This style WG was uncharted waters for me before doing this. Can't believe no one else has torn one of these apart on video.

@@alecaagaard yeah I have to do mine the person I bought mine off of messed up the diaphragm. That also explains why he was having over boost issues. I just assumed it was because he just had one 44mm waste gate on his v8 Camaro.

@@rushking19 Its probably stuck closed. could be from the diaphragm or a spring that isn't working correctly. Mine was the exact opposite. It wouldn't make any pressure aside from the 6psi spring even with my electronic boost controller.
