    Pro XP 1127 Error

    I went through a created a tune but ever since that tune I have been throwing a 1127 Engine Turbocharger 1 Boost Pressure Data Valid but Above Normal Operational Range. In logging I am right about 19-20 PSI of boost and everything else looks good. Is there a table I am missing to up the operational range for the DTC?

    Thanks

    Believe it or not a lot of 1127 codes can be triggered by clutching issues.
