It can't improve power, since at full throttle there is no manifold vacuum to suck bubbles. But you think you did something neat, just look at her bubble at idle!
Make sure to adjust the idle mix- what you have really done is make a vacuum leak, mostly it is sucking air.
Liquid Water injection is a whole nuther point. At about 5% you should see improvements, especially if you have a computer controlled timing that will take advantage of the cooling of the water. You'll need to use at least a gallon of water per tank, up to 15%. Lots of water, leads to some rustiness of throttles and such.
Hmmm, at 10,000 gallons of air per gallon of gas, how many pounds of water are in the air, as a percent of gas, at 90% humidity?
I did put hundreds of water injectors on RV's and pick up in the 80's, and ran one on my 428 Cobra Jet F250 with 11:1 compression. 13 mpg on regular.
