EGR apparently delays the point of self-ignition, so injector timing has to be advanced to compensate. If you remove EGR the injection timing is too far advanced and you get rattle under some circumstances. That is the downside of EGR removal.
Not sure that this is Joel's issue, however.
Yes, the injector advance can be adjusting in the map files. There are also a lot of maps which provide corrections and adjustments for various conditions.
