Ok posted on another site all I need to know is whats needed to run sj xrt pro on my 13. Do I need the Ecu unlock code or the MCC? I can't seem to get a legit 100% answer! I just wanna make sure what I need before pulling the trigger! Thank you

I haven't gotten one yet. Was told certain ones will work on my 13 and certain part numbers won't.
