If your refering to me, dsm95GST, "cross-posting", I don't know what your talking about? Turboeclipse97 and I have two, totally separate inquiries. He's talking about his intake pipe and his after-market B.O.V. made changes @W.O.T. Whereas I'm talking about my actual filter has screwed up the mixture or readings all across the band. Since we seem to be annoying you with our "cross posting" maybe you have some academic insight to this rectify this dilema- no? Anyway, turbo97, the black stuff spurtin' out your exaust when you start is just carbon covered condensation.
