It depends on how much you inject, if you are set up to inject 15% water by fuel then going to 50/50 will make it a little richer (slightly lower AFR`s).

I personally found the best gain running straight methanol (and lots of it!) but this can be problematic with tuning and refilling the meth tank.

Another option is to mix 20% methanol in the fuel tank, but you will need to re-tune for this (add aprox 15% more fuel via the maps), I`m trying this out at the moment.
