    L5P adjusting hiss vs rumble idle

    I got a 2022 L5P that's been tuned and wanted to try different idle sounds. I think I understand the basic principles: Open= rumble, the closer to 0% the more rumble. Closed = hiss closer to 1 is more hiss.

    I found a video of a guy doing it on a 17-19 Powerstroke and he's adjusting a table called "Boost Pressure Control 0 - Mode 0". I did the read file in VCM Editor but I can't seem to find that table. I've included the video for reference.

    Is this "Boost Pressure Control 0 - Mode 0" the same table to adjust on the L5P or is it something different.

    Thank you for any help

    Desire boost pressure or VGT vane control. Is probably what you need to look for.

    I do them on the fords all the time but it?s a totally different ecm.
