You found the only way to use water to increase fuel economy on a gasser, you put together a high compression engine setup like what you have, drive it around normally, with no water injection at light load and use water or water alcohol to increase driveability under high load.
The only other way water might be used to increase fuel ecomomy is to use steam in place of or in addition to EGR.
As far as I can tell no one here is about to do that.

I think I said something like that about a dozen pages ago.
