Word. I hope you get it all sorted
That P1421 will not go away. You can go back to stock and then re-flash, but it WILL come back. You will either have to convince GTM to turn off that DTC or just live with it. I will be going back down to UPREV in a week or so. I will be asking about that one for myself, so I will share the results.
