Any support for 2011 Jeep Grand Cherokee transmission?

I have been having serious issues with the Diablo tune. It gives me a very significant chatter shifting 1-2 and 3-4.
Anyway of fixing this? It's really bad.

are you making any changes when loading the tune?

No changes. The tune is making the transmission chatter badly 1-2 shift. Doesn't happen when i load the factory tune back in. Idk

I have major chatter as well. very little on the 87, more noticeable on the 91 and major chatter on the diablo tune. Im stuck running the mpg tune so I dont damage the trans. Interestingly enough, I can redline each gear just fine while shifting manually and have no chatter. 09 5.7
