Mine says 200 - seems to have worked okay up until now, but I've seen 240 and 280 mentioned, and something about a recall.
Someone with a good memory or kind streak post some info or a link.
I'm lazy today...

I do not know what the pressure numbers were, but if you go to a dealer they can tell you right away via your VIN if your was done or not.
