Don't know if you are running an 2010 automatic tran or not but the automatics seem to dampen the oscillation more that a 2010 manual. I have even seen this in stock but have been easily tweaked out.
In the automatics the idle dive on down shifts to a stop seems to be the more noticeable issue.
Some day I would love to see a IPF tune on a RX system
