Of course I'd have to know where the thermocouple was located during
measurements, otherwise it makes no point in measuring EGTs :-)

Yup, that's the easiest way to install it, given the fact that there's a CO
test tube that can be removed and a fitting to be placed in order to
install the thermocouple.

Yes sir, actually my tuning is more based on the EGTs than on a WB sensor
output, simply because it's not always practical to install a WB O2 sensor.

Well, I have universal adapters for my thermocouple that I use after the
turbine, in place of the original CO test tube (or the screw that's there
from the factory on some ABY S2s and on all RS2s). This way, I know what
temps to expect and what to do in order to correct them.

Nope, very unfortunately I don't....
