Does the CAT sensor heat give you a good indication of the EGT's while driving ?
Yes, it is a slower reacting average temperature. It has several seconds of lag. What we don't know is much lower it is than at the turbo under constant load. I assume, to be on the safe side, there is a 150°F or more drop so upstream temps are higher. We also don't know what the safe continuous limits are. I'm guessing 1200°F conservatively....so 1050°F at the CAT sensor is my continuous limit.

His family has started a fund on giveforward.com. If you have ever been helped by someone else, now is a good time to pay it forward. Here is a link to that page. God bless you! http://gfwd.at/1rz33PW
