    DFCO settings to make car quieter

    I want to make the car quieter while throttle pedal is lift off.
    When going downhill at crusing speed if I do lift off the pedal the exhaust noise is louder compared to cruising exhaust noise level.
    I don't have any cats at all.
    What is a good setting for this in order to make it quieter ?
    Car has been tuned but DFCO settings remains untouched.
    Attached a screenshot of current settings.
    Thanks very much.

    You could disable DFCO, but I think that would make it pop. You could change the enable RPM to 7500 and disable to 7450 or something like that.
