Tuning for a Chrysler 300s 5.7

I?ve been having problems trying to find a tune for my 2018 Chrysler 300s 5.7. I have contacted HP and they stated they have not come out with a tune for the 16-18 year models and may or may not. My question is which I asked also in the email and they directed me here. Can I use a 16-18 Dodge Charger tune on my Chrysler. Same motor, transmission, and etc right? Has anyone tried this or have a opinion if this might work. I?m kind of stuck in a hard place on trying to move forward with my build. Any input is appreciated. Thanks!

Hello Coaster,

This is not correct. You can tune your car but first you have to unlock your ECU and use Dodge 2018+ Smart Access Cable to read and write to your ECU
