I have an ecotec VX V6, is there anything I have to change when putting the bored out THROTTLE BODY on as I have a pod filter setup and one of your plenum spacers?

The throttle body will work fine with your pod filter setup and plenum spacers.  There is a few changes required so I have linked the Mace install instructions for the bored out throttle body for Holden VS - VY, so you can get a better idea what is required.

If you have any automatic though, I would recommend getting a hold of one of our upgraded PCMs as shown in the link below, unless you have a shift kit.
