I think fierocarparts is having some issues with phonedawgz at the moment, but I don't know if anyone else is. He's always done good work and provided good information.
If you change over to the 7730, you will need to swap out to the digital EGR system. Georgia Fieros sells an EGR adapter kit for conversion to the digital EGR. http://www.gafiero.org/shop.shtml
JCircs, did you change to a digital EGR? If you did, where did you get your adapter kit?
