My car hates those effin dynos, it always gets WAY too hot when they're running the tests (ghetto smog place with no fans over the motor, just throw it on there and lets go) and on the way home I can tell the poor car hated it. My best advice to you would be to befriend some persian or armenian dudes who are in the business
Being persian myself, I have some friends who are smog guys and they don't mind slightly bending the law to get my car to pass. My car burns clean and passes the dyno test, but for the visual inspection they just check it off since I have no smog pump or anything of that sort. Anyway, good luck with your whole ordeal.
