I dont have any data to compare but I would think with more air moving across the heater core the temperature would resultant temperature would drop as you are cooling the core a bit and there is less time for that air to warm up.

Another thought, and I don't know how closely it will be related, is that maybe your recirculation pods are not opening. I know on those models there is no recirculation switch like in the later models however I do believe--under certain conditions--the recirc pods open allowing for in-car air to be used for heating.

I guess it's not that cold in Texas, so if you ask me it should be blowing hotter than that on high. Hopefully somebody else can measure theirs and then you can compare. It's -20 here so it wouldn't be a good comparison if I did it.
