factory pcm updates...?
 

So I wanna do a pcmforless tune but I'm not sure if my vehicle has had any or all of the updates issued. They said they can do the factory updates with the tune but it may require a CASE relearn.... Has anyone ddealt with this.? Can someone give me some more info? Do I need the updates? Are they beneficial or will everything ne overridden by the tune?

Talked to the local dealer. Updates only pertain to vehicles experiencing certain issues... No issues=no worries....
