I currently use WM50 to allow proper cylinder balancing of engines based on LOP methodology using my own specification/made EGT probes. Swing between 0.800 to 1.160 looking at rate of change and trimming each as required.

Again another great use of water injection.

Its not known cause I don't share everything, but ~20 years ago I ran 350+rwkw on a 13B turbo at 1 lambda with pre turbo injection, this was by accident actually, but was the first time I had viewed it, the dyno operator could not believe! it and thought his probe was wrong? as there was no way in hell a turbo rotary on pump petrol could do such a thing and live. In the end we did 5 consecutive runs all between 349rwkw and 357rwkw all at 1.000 Lambda or thereabouts !
