For high current and high temperature testing every component must be rated for the environment and optimized. The sense resistor value is very important for the temperature PPM. Also the traces and other non-linearities in the gauge can compound to lead to larger errors.
The max recommended temperature for the gauge is 85deg C.
This seems like a fairly high offset, but all of our characterization is done from -40degC to 85degC, so if you go over this range the deviation could become very nonlinear and lead to much larger errors. The only calibration we can do to help is by making sure the current calibration is as accurate as possible, the other compounding errors are inherent to the device.
