Stock DV with stock spring:
The rubber diaphragm can tear (large boost leak), and the DV can hang open after a shift with the 8spd auto when running 20+ psi at shift with our Stage 2 turbo. We have never seen this on a 6MT or DCT car.
Stock DV with PURE upgraded spring:
The rubber diaphragm can tear. Not real common, seems like it happens to the older model cars with more miles. I assume the diaphragm loses some elasticity over time / use.
DV+ setup:
Doesn't use the rubber diaphragm, holds lots of boost.
