So I'm finally installing the AEM Water Methanol kit on my car. I'm currently on manic stage 2 but remember there was this option for water meth. What does it exactly do and does any one have that add.on?

I think technically the C Map is for 100 octane gas or WMI with pure methanol. I barely feel a difference between Maps B and C honestly. I use meth as more of a safety net.
