    3 bar DBW PCM/ECU '06 silverado?

    Is there a direct swap pcm with dbw and 3 bar sd that would work in a 2006 silverado? My current p59 pcm only supports 2 bar.

    The p59 pcm actually is 3 bar capable but it has low resolution so you can't really fine tune it. I ended up staying 2 bar unfortunately
