where to get an xcal2?

No, it becomes locked to that car and cannot be used for any other car till it is unlocked. It is SCT's way to kill the possibility of people pirating the use of xcals.

Also, there are different not-exactly-compatible versions of the PCM code--that's why the tuner needs your VIN before he can build the tune.

No, that is why you get the xcal2 and pull your 7 digit strategy code straight from your computer. Then once they get that code, they match it to their database of 4 digit computer codes. Then send you your tune.
