As you have surmised, we are basically oriented towards Ford tuning. However, One of my friends at Edge does custom tuning for GMs and could help you out. My concern is that the CTS doesn't currently support your platform. I don't know for certain as I don't really pay attention to the GM or Dodge stuff.
If you'd like to get in touch with me on Monday, I can get on the phone with him and see what's available.
As for Justin, what can I say... he's a helluva guy!

It takes a lot of integrity to be able to do what he did. Not too many folks like that around lately.
I look forward to hearing form you.
Take care and Happy Easter.

Windows™ XP and 7.

Windows™ Vista and

Windows™ 8 is a pain in my a$$!

Windows™ 10 is only slightly less annoying!

Windows™ 11 is garbage!
Much to my surprise, I'm actually quite enjoying Linux!
