It seemed like my smoke trail was getting worse and worse so I dialed in some more AFC tension and that seemed to work pretty good. Then it got bad again and power started to fall so bad I thought I was driving my wifes Mustang GT and boost was way down. After a little checking I found that the bracket that mounts the vacum cylinder on the exhaust brake had broken off and the weight of the cylinder was closing the exhaust brake. After wiring it open all is well again. I sure miss the E brake though. A call to BD has a new bracket on the way at no charge.
