As in the title. Boost gauge only showing a small negative pressure when revving. Variable vane actuator moving nicely so vac system is fine. Turbo is spinning nicely. No leaks in system. I'm bamboozled.

Thanked 4,587 Times in 3,404 PostsDoes it feel like it's boosting? if so could just be the feed pipe to your gauge needs looking at, if not check the wastegate isn't stuck open.

Thanked 64 Times in 60 PostsWhere's the waste gate? There's the vacuum plunger on the turbo working fine when I blip the throttle on the drive. I thought that was what controlled the variable vanes inside the turbo. Am I wrong?
