You need the stock tune to go back to if and when there are any future upgrades. What you are looking to do is to bypass your computer functions for the control of your motor with the pheonix (at least that is the way I understand the system to work).
You do not actually have one chip that does the same a 7 different chips inside your PCM, the system bypasses part of the PCM and you have a selector switch (rotary) to choose the tuning parameter to run with.
I may be partially or completely wrong, I am sure someone will chime in more info.
