Basically once you unlock then you can do what everyone else does to update/change tunes etc. Only thing to be careful of is making sure dealer doesn't update software again.

I’m not sure about other tuners, but my local shop said that they simply hook directly to the ECU with the harness then flash and dyno tune. They don’t “unlock” anything.
Maybe other tuners do it differently...
