    adjusting idle speed on gmpp LS 376/480HP computer

    friend of mine has a 70 chevelle ls l96 with stock ls7 cam and ls3 intake, we are trying to lower the idle becasue the cam is not aggressive and its idling smooth already. dont want it at 875rpm all the time, we tried lowering it slightly to see if anything happened but it didnt change anything, tps stays at 12% at idle
    changed settings in the target idle speed and idle speed minimum tables only
    anyone have any tips? did we miss something?

    You need to adjust "airflow final minimum" too.
