Can I correct with Diablo?

[PCT]

I have a Diablo tuner from Moe's that I used on my '13. I kept it. I adjusted tire size using the tuner on my 13. Can I use the Diablo Tuner on my '19 2500 to just correct tire size? I understand I cant tune it with out a unlocked pcm or what ever, but tire size?

Do you have alpha odb? I think you can do it with that. Not sure about tuner.

Nope, can't do it with the Diablosport unit. You can't access the PCM with it.
