GMs stage 3 kit for the Ion Red Line/Cobalt SS disables AC, do I just need a different PCM to correct?

If I get GMs stage 3 kit, my air conditioning will be disabled. So if I just get an aftermarket PCM like from zzperformance, will that correct the issue? Or is something else in the kit disabling it? Its for the supercharged LSJ engine in a Saturn Ion Red Line, same as in the Cobalt SS.
