Tuning 2019 Mexico Build Truck?

Can this be done and if so will normal base files work? Or will this be different? I can only find US and Euro files

You would have to know what those vehicles shipped with, they may use a US or Euro calibration. If you can see the label on the ECM then post up with the E/C number is, it'll be something like 'IA80041.04'
