Default Weird Boost Gauge needle

It kinda floats up and down under a constant cruise or easy acceleration or even idling. But everything checks out on the Autotap and at WOT its cracked all the way to the right...just an old tired gauge?

I dunno....I have the same issue with my gage. Prolly check the vacum lines around the MAP sensor and go from there?

I had the same thing........

It started after I did the boost bypass mod. I thought that it was a dry rotted vac line but after replacing all those lines and the problem still existing - I pushed the bypass back up a little and it went away. So who knows?
