It has 3 programs on it...I'd like to have one tune for the mustang and two tunes for my truck (street, towing and then stock, right now it has the 1st 2 and "looney" on it plus "return to stock")

It is locked to your VIN until you reload the stock tune.
Then it can tune another VIN, but one at a time.
Then 3 more VINs left. ONE AT A TIME.

Ok, thanks for the info. Now to order the plug n play kit thing for the xcal 2
