    My understanding is that under "Engine Diagnostics" you need to reset the MIL function for the EGR. Per HP Tuners:

    Diagnostic Trouble Code (DTC)
    This tab controls the setting of the MIL and SES lamps and the reporting of the various DTC codes (Pxxx). Note: It does not disable the actual tests. eg. disabling the MAF DTCs will not affect the behavior of the engine if the MAF fails. ie. it will still revert to backup mode, set maximum knock learn etc.


    Diagnostic Trouble Code (DTC) Error Mode

    0 - MIL on First Error: Emissions related. Illuminates MIL the first time DTC sets.
    1 - MIL on Second Error: Emissions related. Illuminates MIL if fault is active for 2 consecutive driving cycles.
    2 - No MIL Light: Non-emissions related. Does not illuminate MIL, but will illuminate SERVICE light.
    3 - No Error Reported: Non-emissions related. Does not illuminate MIL or SERVICE light.

    Diagnostic Trouble Code (DTC) SES Enabled

    SES Enable (Checked): Enable SES/Check Engine/Service Vehicle Soon lamp/display for this DTC
    SES Enable (Unchecked): Disable SES/Check Engine/Service Vehicle Soon lamp/display for this DTC

    In the Chicago area? You could try Speed Inc. in Schaumberg. otherwise they might be some members in your area. I have HpTuners but I live like 3 hours away from you up here in Madison, Wisconsin
