Boost Gauge

[powerstroken]

Insalled my boost gauge about 2 weeks ago and the needle shakes a little at steady throttle is this normal,1-3 psi. It is tap into the elbow not the map.
It is on a 06 f250.

Mine did the same thing on my 03 6.0psd. It turned out the compression fitting on the back of the gauge was a little loose. Check all the compression fittings.
