Im hoping its just the water/methanol thats cleaning it. Currently at 1320cc/min of water/meth (50/50 by mass). Im thinking I'm injecting around 4350cc of fuel ( aussie 98 ). So Im guessing its a 30% to fuel flow by volume not mass. Any richer than this setting and it just lays flat at 6500rpm and stops pulling. When it is leaner it pulls hard to 7000rpm. This is the leanest plug. Sorry for the crap photos. Cheers
