Xcal2 question

[Silver04L]

I am about to sell the Xcal2 for my Mustang to a guy. I set my car's tune back to stock. That is all you have to do to unlock it right?

You have to go online, download liveload3 if you don't already have it, and completely unlock it through there.
I am not sure if the next person can do it, I did it on both of the ones I sold before sending them out. It is very easy to do.
