    ok, I'm in now...

    I set the EGR to OFF. Now I'm in the MIN Vane table, and I see the values are all set to 2.5. So where should I change? I'm guessing the columns of 300 and 800rpm, but how much lower should I go, and how low on the Y-axis?

    THANKS!!!!

    So this may answer my own question, but my hiss is only tuned out "part time". It has a nice low rumble at idle but as soon as I put the truck in gear in goes straight to the hiss. My table is only zeroed to 300-1000 up to 10 mm3.

    Extend that part of the table down to 20mm3 and that will take care of it.

    ditto.
