In my opinion, a 180 stat is a $10 part that takes 5 minutes to install and protects your engine just a little more. Yes it is true the cooling fans won't kick on till 195 due to stock PCM settings, but anything you can do in the meantime to help keep your engine as cool as possible is going to be a good thing.
