I have post turbo also I would NEVER!!!!!!!! go over 1000 post and thats only getting there for a second or 2. 900 is fine. When I'm towing heavy I NEVER over 900. If you plan on going more I hope that you have some money cause you will be needing it for a new turbo and maybe more. Its better to be safe than have to spend a few grand.

pre-turbo is irrelevant in this case. he's mounted his already and chances are he isn't going to change it. the max save temp is 900-950*, and i wouldnt go near 1000* for more than a few seconds.

I'd keep it under 900 to be on the safe side. If it hit's 950 for long, you're asking for trouble. I know you've already got it mounted post turbo, but if you get the chance, I'd try to move it pre turbo. Drilling and tapping the driver's side manifold may sound a little scary, but it's not that tough to do.

I've reviewed many of the posts describing "safe" egt's for post turbo pyros. They seem overly conservative for me...
Pulling my trailer (6500lbs) with a stock 02 7.3, I consistently get egts in the 950 range for prolonged periods on small inclines. Steeper hills I could easily push it upwards of 1000 without trying.
Seems to me that if my egts return 950 with a stock truck, then getting upwards of 1050 may be normal?!?!?
