So I figure running an afr in between these would be correct, so around 9.5afr or 0.65 lambda at 50/50 meth/fuel. So Im at around 9.8afr to be the same so 10.5 is still leaner. I tried leaning it out to 11.2 at the track with no gain in et or mph so I richened it back up. Also the plugs lost there fuel ring which scared me a little lol. I understand the water does its thing but at some stage you would have to go richer than a lean gas scale reading. Cheers

Unless you want to pick up parts off the road or track keep it with 40% to 45% excess fuel mate, real world always trumps theories and performance validation is king.
