Water Meth on Ecodiesel

Has anyone done it? Recommendations on where to install the injector? IS 375 ml/ min too much?

I would install it in the block off plate from the EGR delete, no idea if that is the best place or not though, just the easiest to put in in and it get to all cylinders.

I was thinking the cast aluminum piece after the charge pipe from the intercooler. Tapped on it today and it feels thick enough to drill and tap. Will be using the block off plate for a boost reference if I can't find anything easy to tap onto but I think it wouldn't spray the cylinders evenly since it is already in the intake plenum, would be a little uneven ya think?
