Today I was looking at my cats after a few minutes at idle and they were glowing really bad, also the Ypipe after my dual cats where starting to glow.

Timing set to 32 deg @900 rpm WB showing 14.........

Not terribly surprising as with a lopy idle you have lots of little missfires that the cat is trying to clean up, hence it's overheating. I'm afraid I can't help you much as I've never understood how people get cats to live under these circumstances. Hopefully someone else can help you more.
