Hi Eliacim,
A doctor (or a nurse) physically checks your pulse and then listens to
your heart with a stethoscope when evaluating one's health. Similarly,
both the CHT and the EGT give different perspective as to one's
engine's health while it is operating under load in "real time". You
"gain information", but how much use that information is depends on
your understanding of our little Continentals.
Such information is valuable not only for trouble shooting, but also to
operate with efficiency. The proficient pilot can lean more
aggressively and effectively by knowing conditions to avoid, and can
observe advantages and disadvantages (in terms of rpm and related
power) of a particular setting at various cruise altitudes.
Since winds aloft can vary considerably with altitude, the "bottom
line, here, is always going to be the "best" ground speed (or available
range) according to a GPS.
Regards,
WRB

Need advice.
After a major overhaul 4 years ago, I installed a 4 probe CHT. The CHT
is meant to be a troubleshooting tool. If one cylinder was going bad
for some reason, I could see the difference in temperatures and know
where to start troubleshooting.
Now I plan to install a 4 probe EGT, with the same purpose.
The question is, for troubleshooting purposes, am I gaining
anything by having a 4 probe EGT, in addition to the 4 probe CHT?
