One other consideration -- you won't just be able to swap the PCM back and forth at will. If you are going to leave it in the other vehicle, it will be okay eventually, but it takes a while to learn the new map and tune your setup specifically -- like somewhere near 500 miles of driving -- or at least that's what mine took after having the power disconnected for a while.

Just get another tune... They're not that much money. :thumbsup:
