I was able to get launch control added to my non-STP RT+ but I posted it in the trans section by accident.

If anyone has a stock tune of an 2015-2016 RT 6M with factory equipped STP I am still looking for one. I am curious to see what is done for launch spark which I am sure is different from the Scats.
