Bringing this post back from the dead again. The car is put away for the winter now but I can still get some new info.

I run the M7 nozzle (I think, I know it's the middle one that comes in the kit). So when I run the car without meth, I run 11.5-11.8 afr at 16.5psi and 16 degrees of timing.

With meth added it brings my afr down to the low 10s so I lean my fuel out with my tuner and bring it back up to 11.5 - 11.8 on meth. I'm able to run 23-25 degrees of timing WOT on meth. (50/50)

Does this seem right? Any richer and it seems sluggish. Never went any leaner.
