The kubota engines run at about 14% thermal efficiency at 2kw load.
The problem is nothing is going to make them much more efficient when spinning at 1800RPM at 1/3 load.
It doesn't matter how many GEET reactors or HHO generators you bolt on to it, they will do nothing to get around the pumping losses.
A turbocharger would be the best thing for them.

Seems to have given me a +2mpg boost just driving around town.

Its not unicorn material at all.
I have priced it and its out of my price range, if the units I saw are even for sale yet.
