Because It's awesome, that's why!
You can adjust way more w/ TB. Plus it doesn't stay on your bike. But, if you feel more comfortable tuning (and your buddy does too) w/ PC go right ahead.
From what I understand, and I could be totally off base, PC intercepts the signals going to your EFI, and basically tricks your stock ECU into doing what it wants.
TB allows you to reprogram your ECU, changing everything from fuel to ignition, to AF targets, speedo constants.....
Basically if your ECU controls it, so does TB. It also allows you to diagnose/clear trouble codes. Very cooooool.
