Well now you have established a base line.

You made a lot of changes to the carb. and sounds like you have tuned the engine up so you should see gains in that alone without the use of your hho generator.

So now you should do some aba test with and without the hho generator.

This will show you if your hho system is improving on economy or not.

Good Luck and let us know your findings.
