Thanks for the links. But there was not anything in there about long term satisfaction with the product. Mostly about how old one of the posters is and more about how long ecode takes . I'm looking for specific feedback about people getting DV codes and CEL. Also, re: the install, the instructions call to tie into the brake boost line for vacuum. The audi tech who installed mine used a jack going directly into the intake manifold. Any thoughts on that?

Thanks
