Re: water methane injection
Im injecting it into a tb spacer and before I tuned I ran an 11.7:1 AFR and when I sprayed it on the same tune I ran 10.9:1. I now command 12.3:1 to get my desired 11.7:1. I'm on a 5gph nozzle, so not too big but still adds a fair amount of meth. If you inject more fuel to the fuel thats already going into your engine, you will run a tad richer. Not big time, but noticeable on a wideband.
Stealthee is right though, it lowers charge temps so you can run more timing, and of course boost without getting knock.
