Yeah, something to do with the owner somehow feeling he can be held liable for "discussion of conspiracy to remove federal mandated emission equipment" if the man ever cracks down. But considering any ecu tune, nozzle change, and muffler delete is also illegal according to tdiclub's rules, I find the latest round of no dpf talk to be total crap. Either allow it all or don't allow any. Don't do a drunken stumble down the line.I know I am a member on there but it's not going anywhere. I guess like you said they don't want to talk about it. Lol
