My boost gauge has been giving bogus readings lately I think. When my boost is completely off (with manual boost controller) the gauge still goes up to 5psi...and when i turn on my boost to around 2psi on the controller my gauge reads up to 15psi...which is totally bogus.

I checked the vacuum line from the gauge to the port on my intake manifold and everythings tight and there doesnt seem to be any leaks. this is a faze mechanical boost gauage which reads vacuum and boost btw.

thnx
