    Should be fine as long as your check engine lite is not on. Ryan

    As long as the check engine light isn't on, and the tune did not outright disable any of the emissions monitors, you will be ok.

    Yep . . that is true . . with the OBDII testing if your car's computers "senses" everything is in working order you will pass.

    My 2000 Camaro SS with heads, cam, long tubes, air intake, computer tune and what not passes everytime.

    You should pass with a perfect score. My tune is burning cleaner than stock.
