I had to turn mine off when I was getting it dyno tuned because it was dumping too much fuel in and making it too rich.
I've been running with mine off for about 10 months or 10K miles and seems fine so far. I'll find out if it hurt them when I get out to removing them for the headers.

So, would it be better to tune with the COT off and then turn it back on for normal driving (to save the cats). Understanding that I could lose some performance when it engages.
Has anyone have documented cases when the cats failed from running with the COT off?

Unless your boosted, spraying nitrous or running lean at WOT, turning off COT on a stock engine is *relatively* safe. Logging data on the street, COT will sometimes kick in right after the 2 > 3 shift on my SSS.
Tuning with COT off and re-enabling for the street would be a good, conservative plan.
If you're looking at more mods in the future, a $100 pyrometer is a good investment after the WBO2.

Thanks Stealth.
For the street I will most likely leave the COT Enabled, but I may raise the enabling temps up 100 degrees for alittle more time before it kicks in.
