Its a Snow Performance Kit (not Alky Control). Go to their website, or give them a call for more info on it if you want.

You can rig up the light however you want. However what I use and believe works best is to set it up not to the pump but to a sensor that actually senses the meth flowing. I have another light also rigged to show me when my meth level is getting low.

I did a few more runs last night, and did notice that the wideband does tend to float around while in the upper boost. This is no doubt because of the increase in meth as the increase in boost. I did see it climb to 11.9 at one point very momentarily, and I didn't really care for that. I have heard some running a tune that lean, but I you have felt better if it didn't. This was really only for a fraction of a second, and most of the wideband readings were back to the 11.5 range.

Perhaps I'll consult my tuner.

 

Ive done some reading on that already, it seems the meth is the cheaper route in the long run if you buy in quantity i believe.

 

11.8 is a ideal afr imo. I wouldn't push it past 12.

Safe afr without losin too much power to a rich tune would be 11.5
Less than that is just too rich and your wasting fuel and giving up power.
