Charles finally got back to me again. Here is what he had to say and it looks like we can go ahead and get our PCM's.
ZZPerformance Group Buy Issue
chris,
I apologize, but i was out on vacation and was not able to answer my helpdesk
tickets.
Tell zoomer that i said its ok for him to take the alero orders (6 cylinders.
(not sure if there are 4cylinder aleros but just in case, NO ! 
) ...
I will need VIN # for each vehicle and if possible the hardware # on the pcm
itself.
thanks !
Going to call Zoomer at ZZPerformance today and verify everything. Getting excited again.
