Great work ztan. The community appreciates it!
For those of you on B01C, this is what I sent to Shiv:

Note that I have set this .xml description to "boost" pressure in psi over atmospheric. Use the descriptor at the top of the post if you work in absolute Bar.

B01C:
Code:
    
    <table name="Boost Limit (Fuel Cut) enable" storageaddress="69171" />    
    <table name="Boost Limit (Fuel Cut)" storageaddress="10E5EC" />
    <table name="Boost Limit (Fuel Cut) Resume" storageaddress="10E5FC" />
    <table name="Boost Limit (RPM) Active" storageaddress="10E600" />
    
    <table type="Switch" name="Boost Limit (Fuel Cut) enable" category="Miscellaneous - Limits" sizey="1">

    </table>
    <table type="2D" name="Boost Limit (Fuel Cut)" category="Miscellaneous - Limits" storagetype="float" endian="little" sizey="4" userlevel="4">
      <scaling units="Manifold Pressure (psi relative sea level)" expression="(x-760)*.01933677" to_byte="(x/.01933677)+760" format="#0.00" fineincrement=".01" coarseincrement=".5" />
      <table type="Static Y Axis" name="Boost Limit Fuel Cut" sizey="4">

        <data>On Above</data>
        <data>Off Below</data>
        <data>Off Below</data>
    </table>
      <description>These are the MAP values at which the boost limiter is engaged and disengaged. When engine speed is equal to or exceeds the 'On' value, fuel cut is active, after which, if engine speed drops below the 'Off' value, fueling is resumed.</description>
