Finally got the boost gauge actually moving somewhat properly on hose 11. Question is, what psi is it supposed to read at idle, normal driving, first and secondary turbos?

I currently have 20psi vacuum on idle, hitting about 10psi boost on primary, then drops to about 5psi boost in the VOD, I have yet to see it on the secondary turbo. When moving and the foot comes off the pedal it drops right back down to 20psi vacuum.

Pretty sure 20psi vacuum isn't right but the primary and VOD look about right.

Any help would be greatly appreciated.

? didn't see this post before, might be the sensor unit if it's one of the gauges that has one. or an interference with it in the wiring mine fluxated a lot like that turned out one of the wires was touching another one gave it some problems but sorted now.

Well if that equates to about 11inhg (inches of mercury) on vac then id say its right as all my previous cars have been around there too
