    What is your idle?

    I am curious i have seen threads where people were talking about their car idling at low rpms after different mod installs? So now I am wondering what rpm should our cars be idling at?

    Yes.
    Depends on the cam, the tune, the cubes, etc...


    The cam itself won't change the idle, you have to have it changed.

    ~800 after the cam. It can go lower but it gets pretty rough that even I don't like it.

    You're fine. Once warm there's 2 different idle speeds, one for Park/Neutral, and one for In Gear/foot on the brake for A4's. On a scanner stock mine was 645-676 P/N, 525-585 in gear. Tach was pretty close at idle.
