EGT age?

[745 turbogreasel]

Do the senders  fade out as they get old?

My 'Burb has a Banks(Hewett Instrument, 1999 I think) non electronic gauge, and its response seems slow as can be, as well as it rarely hits 800...
Then again, there is no smoke, and boost response is pathetic just like the last motor which showed absolutely no sign of EGT damage.

My D24 has an electronic gauge, and it responds almost as fast as you move the pedal.
Both senders are at the turbine inlet.
Either I have  conservative tune, faulty instrument, or both...

So, my question is what is the failure mode?

Nobody had one die?

umm, figure out what type of thermocouple or whatever it is..  maybe k-type?

see if they break down as the age.
