Juan,
Not being an engine guy, I'd first exchange the sensor with another
cylinder and try that.
Then, consider why the mixture might be leaner on that particular cylinder.
i.e., consider how more air or less fuel might be feeding into that
particular cylinder.
and lastly, perhaps how that cylinder's exhaust manifold may be
different from the others as proximate
to internal exhaust flow, valve gap and firing order, etc.
This is not likely caused by external temps, airflow, or cooling, but
should be found as an internal
issue driven by the internal mechanicals.

Question to the Engine geniuses on this site. My CHTs are all reading great, between 267 and 280 on all 6 cylinders on my Jabiru.
Number 5, the right rear most side has an EGT of 1400 and all other EGTs are reading 1300 to 1320. so they read as follows
EGT 1310
1320
1315
1315
1400
1320
Why are the CHTs running great but the 5th cylinder EGTs running hoter by 100 degrees than rest?
Anythoughts?
