I have a 17 Silverado 6.2 A8. I wasn't happy day one with how the truck ran, shifted, etc. I started logging and making small changes which helped. The biggest help was getting a new TCM and then having HP do their thing to it. I was able to get the truck to run the way I want. No more weird idle issues, no clunky drivetrain and the throttle response is night and day.
I did find that V4 mode would activate at times and not register on the dash. Only caught it while logging one day and just happened to notice it. Not saying that is your issue, just something I noticed. I attached my most current PIDS list, so modify as needed. I do use this truck as a test mule so there are dual widebands permanently mounted and an actual ethanol sensor wired in and functional. This list should get you ready to sort through more data than you may want to see.
Good luck, keep us posted.
