The so called "danger temps" can be somewhat misleading. The TRE probe is a good investment because it reacts so quick but it shouldnt be your only tuning tool. For example: When i was having problems with phantom knock, i could leave a light and even at partial throttle, my EGTS would sometimes exceed 1600. Now was i in danger of blowing my motor? No. But the timing being pulled by thwe false knock was causing super hot exhaust gases/flames to be shot into the manifold. I wouldnt have known this was happening without a logger showing me the 43 counts of knock. Since the TRE probe reacts so quick, by watching it, you can see if there are any drastic jumps in tempature over a range of say 200-300 RPMs. Any rapid jump in temp, even from say 1300-1500 is a sure sign of knock. Even though you havent reached the "danger temp" its a good idea to get off throttle.
