If EGT is the case, then bump up the max egt setting on the unit. If it will not go any higher, try relocating the thermocouple for the pyrometer to the downpipe. this will lower the reading.
If you do this, it would be in your best interest to put in a secondary pre-turbo pyrometer and monitor it yourself. You dont want to get it TOO high.

a stock diesel can stand 1500deg for a few seconds, and ive seen many stock cummins push the needle to 1700-1800 for the length of a pull, and drive home. they do it over and over and it used to scare me too, but it seems to be ok
with an airesearch, but schwitzer's are more sensitive. all i use are airesearch(garrett) and thats whats on my '031500 is def the limit for a stock diesel tho...if u go for long times at 1500 u may get problems
1300 is a good street limit for towing ang such

I understand. Sure for a second or two those temps aren't that scary. I come from an construction equiptment diesel background. If say a track type backhoe is just steady throwning dirt at WOT (2200 rpm) and I happen to point my infra red thermometer at the turbo's turbine section and it reads 1250+ and I dont tell the operator of the condition and he continues, I know I'll be replacing the turbo shortly thereafter. I've pulled them off and have seen no turbine blades left. And the operator wonders where all the power went!
