Default P0200 code what next?

Ok so I have done all the tests I can think of to check the injectors:
I checked 12v ignition at each injector. Good on all
I Used a Noid light on each injector and it lit up like it should I will post a video
I Ohmed each injector 1, 3, 2, 4, 6, and 8 were 12.5 5 and 7 was 12.2
What do I need to do next?
I am going to clean all my grounds and add one extra just in case.
I have 2 sets of flex fuel injectors that I can try but then I would have to have the tune changed. I don't have the ability to change the tune right now.
I pulled the plugs and all of them but #6 looked fine, 6 was real black. What would cause that?

I had the same problem with 2002 SS. My motor would sometimes run verybad and flood at idle. I had to rev motor high to clear plug #5. Scan showed P0200 code. Turned out I had a short. Wire bundle exiting computor was rubbing against sharp edge steel on fire wall. I simply pulled wires away from firewall steel lip and wiggled all wires going to injectors to fix problem. I also tapped on computor using rubber mallet and wood dowel. So far so good. I hope this helps.
