It is simply a testing protocol. You have to understand the test to absorb the implications. It is used by such well known manufacturers as Bully Dog Programmers and government agencies such as the EPA. It is used by colleges and universities.
The basis for the test is the use of a baseline vehicle run alongside a near identical test vehicle. Several runs provide a baseline for both vehicles. The test vehicle is then run several times with the test system/device active and the baseline vehicle running along. The baseline vehicle provides a "sensor", if you will, to provide feedback on any changes in variables such as temperature, air density, etc. These changes in the baseline vehicle are applied to the test vehicle.
Performed correctly, the test is conclusive down to a +/- 1% accuracy.
The fellow who ran the test in this instance , C. J. Travis, is an elderly gentleman who is/was a consulting engineer and allegedly had a hand in developing this test years ago.
The test can be administered by any number of qualified consulting firms. It must be pointed out that the test and it's results are the property of the paying party. Thus, all you seem to find on the net about this test are the glowing positive results. I am quite sure there are many failures that never see daylight.
