2023 5.3 w/10spd DFM Disable

Too late. Already ordered the RA007. More expensive and doesn’t have the OBD diag functionality of the Carbyte but that’s fine. Read all about OBD and ECU connections and 40mpg plus activation vs 0 cyl/coast and so on. All the debate etc. But made my choice. I’m sure I’ll be happy ‘nuf with it.
