Beat the **** out of it prior to the test to get the cats smokin hot, do not shut the car off while waiting in line, manually raise the idle just for the test.

What wait says, also I would have fresh oil, hotter plugs and a high idle..This is one of the reasons that from the factory the temps are in the 220-230 degree range to help emissions...
