Im not familiar with the 04+ PCM's to be able to accurately answer your question unfortunately. Maybe someone with some experience in tuning those will step in here and help out. I cant imagine the 04+ being that much difference in that regards, but having a tuner would be an easy way to tell.
If its not turning on at 180* then Id definitely say that it was not programmed. I bought my PCM specifically for that reason because at the time I was running a tad warm because (at the time I didnt know) I had a partially plugged radiator thanks to Dex Cool.
