Boost gauge flutter (bad)

[strokin629]

Question about my boost gauge any advice would appreciated. My boost gauge flutters extremely bad to the point where it's very loud and annoying to drive .Between 0-10 psi it's minimal but there, and from 10-32 psi it's so bad I can't even see the needle it's moving back n forth so much. Doesn't seem like its affecting the performance of the truck and has been doing it for a long time, any ideas? And it's a 0-60 auto meter gauge

There is supposed to be a restrictor that slows the air flow and surging to the gauge. The barbed fitting that goes into the intake elbow should have one unless you tied into the MAP sensor hose where the "T" fitting should have a restrictor built into the outlet going to the boost line to the gauge.

I did tie into the MAP sensor and there's no restricted I will change this tomorrow thank you!!! Very much

No problem. The "T" that has the restrictor in it will have like a little brass piece in the end of it that takes the opening of the tube from say 1/8" to under 1/16". It just basically smooths out the air flow to the gauge so you don't get any of the jittery readings.
