I'm experiencing the bypass valve releasing boost at WOT just before it shifts (a6 car) it may actually be causing it to short shift. Trying to figure out what would cause a bypass valve to fully open at WOT over 6k? Talked to procharger, they said it could be the diaphragm in the valve so I'll have to check that but was wondering if anybody else ever experienced anything like this or has any other ideas?
