    The "updates" are the lateast and greatest EPA low NOX settings, You don't have enough posts to PM Mr.Haney he is THE man to talk to. Ask a moderator to contact Mr.Haney for you, he will fix you right up.

    While you waiting type Mr.Haney into the search box, and start reading, then you can decide for yourself. keep an eye on your Private message box, thats where he will send you his contact info. When he gets done your face will hurt from grinning.
