    "Dash Pot" Adjustments- Don't see a table

    When my foot is taken off the accelerator pedal on my present engine ( at any cruise spped), the RPMs return very slowly to idle.
    The HP Tuners editor does not allow access to a "dash pot" table in the PCM programs used with the GM 3800 V6 engines. Does anyone know where in the program there might be a table that I can make adjustments to in order to speed up the rate of RPM decay at closed throttle?
    I attribute my problem to be a result of the larger N* TB that was added. Recomendations are appreciated.

    In the PCM's I have done, that is controleld by the min airflow table, with mins for rpm for each gear range. Just need to reduce them in the gears vs rpm's where you have the issue.
