TCM and PCM updates

[5thgencp3convert]

Hey I’m new here and this is my first post and I’m curious I have a 2019 3500 aisin HO it is deleted and tuned would the new TCM update mess anything up? (I’m assuming I have to retune after the update) thanks for the advice y’all!

Hey new member so I hope I’m not asking a dumb question here but with the TCM and PCM update for the 2019 aisin HO engine would it damage any part of the truck if the truck was deleted? Or after the update just reinstall custom tune?

yes and yes

Why would you want to update anything? I still have an outstanding VB6 recall on my truck. Tookit for an oil change and literally told them not to fcuk with it as it runs so good the way it is. They whined about it a little but didn't touch it. If there is a safety recall of some sorts I'll probably do it but other than that they can shove their PCM updates where sub doesn't shine.

Be very surprised a dealer would do a flash on a deleted truck unless you know someone at said dealership.

Wouldn't the flash erase the tune?
