...simple water-vapor (bubbler) systems typically 'lean-out' the A/F-mixture, depending upon *how* the water-vapor is introduced into the engine...by manifold vacuum or by injection.

...diesel people will agree that water-vapor can & does (good!) help remove carbon deposits from within the cylinders...but (bad!) it also tends to eat/attack steel components with vicious pitting of exposed surfaces.
