Why is my VIN still there?

[Razzaa]

I sold my tuner and returned to stock before i sold it. That should unmarry it correct? The person who got it just messaged me and said my VIN is still in the tuner. Will he still be able to recalibrate and use it? I followed all the instructions to unmarry it properly.

did they actually try to tune the vehcile?
Showing a VIN does not mean anything...
