Interesting comment. I have an EGT readout as part of a tuner on my diesel pickup, but I haven't paid attention to response speed. Next time I drive it, I will study.
I think that if I buy something as a tuning aid for my bracket car, an O2 sensor with some sort of recording capability would be more useful.
You won’t be able to see the response speed via a gauge. The gauge will have a much slower response time than the actual thermocouple will. Most of the aftermarket egt probes are in the 140 millisecond range.
