Tuning to or for temps is crazy, I don't do it and i don't recommend it.. There is absolutely no point in trying to achieve a certain engine temp.. it defeats the whole point of tuning the engine

A temp reading can be a rough guide or give you some basic reference at best

Tune your engine by how it sounds and performs.. nothing else

Usually around Australia we see happy tuned engines produce temps of around 100 - 125c, Sometimes they don't clear 85/90c.. sometimes they hit 145c and pending the environment they are in and how they are been used and with what fuels etc this is all fine

One other thing, on a race day grab five peoples temp guns.... and see how much they all vary by
