I have an 2011 automatic that has the idle surging some, with three different tunes made by three different tunners. I don't have a Bama tune, maybe all tunes surge at idle. I had the idle surge even before i installed my BBK long tubes with a catted x-pipe with my old tunes.
I've cleaned everything that can be cleaned and nothing has helped. Guess its something we have to live with.
