I have a 2001 Camaro. Can I upgrade to the 12212156 OS? Why I wanted to is so I can upgrade to OS5...

yes, you can.

But I believe all you really need to do is update straight to the Custom OS 5, and use the 12212156 .tun file to flash the calibrations into the PCM.

There ya go Bill, welcome to OS5 land :) If you want to take your existing calibration over unfortunately it will be a copy/paste exercise.
