I have a 2018 Trackhawk. I kept my MPV1 from my Charger HC after I got rid of it. I know the PCM has to be hacked to tune it. Does it need to be hacked just to do some bone stock datalogs? My TH goes pig rich at 5K rpms stock. I want to see if it's Cat Overtemp that's doing it. Thanks in advance.....
