Supercharger boost spike?
#25
Okay tried on the way home and pulled what I thought was the VICs connector (2 pin connector at the rear of the intake with a small vacuum pipe next to it)
The problem is still apparent, I hit 12.5psi and my boost gauge hit ~10psi. My pulleys are 65/110.
Did I disconnect the correct connector for VICs? I pulled the one circled on the left. There is one above that with what looks like there are 3 pins to it, but it was dark and 0*C outside so I didn't hang about.
Halp!

I don't think there is an electrical connector in the region of the actual actuator circled on the right Richy?
How else can I be sure I'm 100% completely disconnecting VICs - pulling and plugging the vacuum line?
If I had a partially blocked CAT or restriction in the exhaust then that would likely produce a slow build up of boost as the back-pressure rises with increased RPM. Another suggestion has been a sticking valve but surely that would represent itself in a similar fashion to a blocked exhaust and not manifest itself as on/off at 6krpm every time?
