Thanks Mike, I appreciate the offer to help and if need be will be in touch. There is a good Cummins dealer pretty close to me, I've worked with them before but always seem to forget them as a resource. Now though the EGR is taking a back seat as it looks like my turbo is heading south. The ebrake is acting up and its popping codes, only about 380,000 hard working miles on the truck with little or no problems so I guess I cant complain too much. I'll pop by the Cummins shop, if I end up needing anything I'll drop you a note.
Thanks again,
Ed
