This is the reason why many replace their 195* thermostat with a 180*.
I don't know if your 2000-2005 has a 195* 'stat, so someone else will have to chime in on that.
Others, with highly modified and supercharged engines just want to keep the engine temp down some, as things get pretty hot in there with boost.
Drilling the 'stat allows bypass flow during early stages of the warm up and extra cooling and also helps to keep from trapping air in the system after a coolant change (a common problem with our bonne'*).
Here, read this thread. It has good info, including the T'stat change and drilling info.
