A load of camping gear, but only two people. Not really a massive weight. I guess it's hard to compare with probe positions etc. My probe is probably a little off centre as I had to get a coupler in place to fit it and it doesn't go in far enough.

O.K.educate me it seems you guys are scared of exceeding 500 deg . is that c or f and why so low when driving road trains we played 1200 to 1400 f. I think; were they measured differtantly .

Temperatures over 500 degrees Centigrade (continuous) EGT measured post turbo is considered a rule of thumb as risky temps for ZD30's.
No totally black and white technical reason for 500 Deg and certainly factory settings will regularly exceed that.

Post turbo temps are not a very good guide to peak combustion temps as you kind of have to guesstimate what the delta T is for the temperature loss over the Turbo. Pre Turbo is definitely the way to go but a tougher installation of the probe so not many bother.

1200 to 1400 farenheit in a truck engine doesn't sound outrageous to me.
