Dead easy, if you have a control car with its own factory EGT sensor so you can pop one in next to it and test it.
I've found Decent quality non powered K types are all pretty good, it's only the thermistor and RTD types I've ever found to vary greatly.
To be fair, 90% of modern cars already have them as standard so monitoring temps while mapping stuff is an absolute doddle.
I normally use the snap on verdict for such work as it's wireless so I can go and sit in my office and monitor temps with a brew when the noise gets too much. Lol
On this image I was monitoring temp before DPF, temp before CAT, exhaust back pressure and charge temps.
