Turbo boost gauge

The turbo is always called for, that is it's always working making boost even under very light throttle because the exhaust is always going through it and spinning it. Even at idle it may make enough boost to make the needle sit just above zero. If it doesn't read anything unless you stomp on it then something is wrong.

Scott I'll respectfully take your word for this as I'm not a diesel tech. I have had my current unit for 9 years now and my gauge rests at zero absolutely at idle as well as highway cruise. I watch all my gauges so I'm quite sure of this. It will jump only under a hard acceleration. I mostly baby it so I rarely see it move.

Bad gauge.......bad sensor.......bad tubing

If it was turbo you would have major problems getting up to speed, accelerating, climbing grades.....driving. The turbo is what packs the air into the combustion chamber.
Lack of engine power, huge exhaust smoke (black or blue), oil consumption etc.

Bad gauge.....bad sensor....bad tubing (if mechanical not electrical)
