yeah i just passed my EPA today. yay..
all they check is BOV, boost contoler, thay you only have 1 intake mod, emmisions levels<that you have a cat> , nosie and that you have std ecu<via console port i think>. They are pritty nice guys after they were done my mate tried to convince him that the pfc could have less emmisions than the std ecu.. haha
Did you know your allowed to have a pfc if you pass a full labratory emmisions test. too bad the test is 4k per try. <_<
