    I have done the 3psi pully for the supercharger and I also want to do the super dampener for the crank shaft but is say further programming required

    Does anyone know about that

    If the damper is not the stock size, you'll need to tune again for the upper and lower pulley.

    Do I need to tune if I only did the top supercharger pullie? I didn't see anywhere it said to do so.

    When I get the lower dampener what is a good tuner to use?

    yes, as the limit is set to like 11.6 psi. You won't benefit from the new one until tuned. Also some kind of fuel mixture change I believe. Call HHP

    Anytime the level of airflow through the engine is changed (like with the addition of a smaller supercharger pulley), the PCM must be revised accordingly. Otherwise, a dangerous lean condition could result.
