Water boils under vacuum, most of your "gas" was water vapor.

Here's why a vacuum applied to an HHO device produces more GAS.
Inches of Mercury - Boiling Point of Water °F
26.45 - 120
27.32 - 110
27.99 - 100
28.50 - 90
28.89 - 80
29.18 - 70
29.40 - 60
29.66 - 50
29.71 - 40
29.76 - 30
29.82 - 20
29.86 - 10
All values are at sea level. Subtract 1 inch for each 1000 ft. above sea level.
If you want to accurately measure how much HHO is being produced at a vacuum then turn off the HHO Electricity and turn on the vacuum pump. Check your flow meter. Write the flow rate down. Then turn on the HHO Electricity. Write the flow rate down. Subtract the first number from the second number and you get the HHO production rate. By subtracting out the first number you are dismissing the rate of flow produced by the vacuum alone. I'm guessing that most people are testing outside at near 70 to 80 degrees. For water to boil at that temperature you must put between 28 and 29 inches of vacuum on the system. Remember to calculate in your elevation. 1000 feet above sea level reduce 1 inch of mercury.
Please do this prior to posting that your system gets better HHO production under a vacuum. If it does, it does. If boiling water vapor is the source of some of the gas, you need to know it. It will affect your automobile's engine.
Smith03Jetta,
Took flowmeter measurements with unpowered gen. Readings were about 1 to 1.25 lpm.
Took flowmeter readings with gen powered at 8-9 amps. Readings were about 2.25 to 2.5 lpm.
Looks like I am generating a little over 1 lpm HHO at 8-9 amps.
The flowmeter I am using is really borderline for the flows I am measuring, that is why a range and not a value for lpm.
I think the water vapor also helps mpg, and the truck runs fine.
BTW, I connected a vacuum gauge to the intake. Highest vacuum reading observed was 21 inches, right after reving the engine then quickly closing the throttle plate
Also boiling point of water at 21 inches of mercury = 156.75
