It depends on where ur probe located in ur dump pipe. Mine is just below the sheild/cover. on standars i got mine to 520. With the chip i got it to 566 up a hill with a one tonne boat. The temp on the day was 20 degrees. I've set mine on 575 degrees.
I was informed that the thermocouple position in the dump pipe doesn't make a huge difference to the reading.
When gas it expands it loses heat so I would consider 100mm max away from the turbo a good position, or anywhere you can get the damn drill into without having to pull the exhaust off.
Without the aid of CFD modelling I imagine the temperature profile through the dump pipe would be difficult to calculate, but you could assume there is a lot of turbulence so the temperature gradient should be rather uniform.
