thanks.

aircare colorado runs the tests on rollers, running vehicles through a series of speed changes.  sometimes the tests are pretty quick, sometimes they are running it for several minutes.  i don't know if they look at rpm, or if they just watch the speed and shift as appropriate.  the test results are at home.  all the other pollutants were low, but none of them anywhere near as low as my '03 2.0 golf.
