    I was wondering if the air line could be clogged?
    I checked for kinks in the line and none found.

    Is it actually boosting?
    Is this a gauge issue or a performance issue?

    you didt say what kind of truck or the year, on the newer trucks, evering thing is on a sensor. I have a 2007 international, and the volt gage started reading funny. The whole panel of gages had to be replaced, its all hooked into the computer

    Get your CAC tested from the right side that will pressurize the complete system. You can check, a lot of connections, gaskets, blow-by, and also the boost gauge.
    Just a thought!

    How does the truck run? The guage do go bad from time to time. If you don't notice a difference in performance replace the guage. I just replaced mine two months ago. It was reading 20lbs less then it should. This is only if the line to the guage has no problems.
