Yeah both have been done.
Repinned the coils and injectors on the harness and reassigned the injector banks on the tune. The injector bank assignment is just for the o2 sensors, there's no way to change the firing order in the tune.

The dizzy could be out by a tooth or 2, but it should come up as a DTC if it's out of sync I think.
