Performance Shift

So i added the Performance Shift today to my DHP 1.0 PCM on my 2002 GTP today using the how to write on here. I have it wired to a switch inside my car. My question is, how do i get the PCM to recognize that i added Performance Shift to it. Do i need to have it flashed with a tuner? Or can i do something on my own without a tuner to activate Performance Shift in the PCM?
