i got about the same numbers when the stock cat was on for emission back in December.... well to be exact, here are the numbers
idle at 678rpm:
HC ppm reading: 5
CO% reading: 0.00
40km/h @ 2932rpm
HC ppm reading: 4
CO% reading: 0.00
NO ppm reading: 1
it was with af/x udp, aem intake, borla exhaust, bosal flex, crower stage II cams, kent cam gears @ 0, 0, ported 00 intake manifold, ported TB, 9mm plug wires.
so I'd say our stock cat did a really good work on cleaning the exhaust gas.
