Ok good to know. I did not do that. Can that be accomplished by using Insite? What kind of concequences will I suffer from not changing the code in the ecm?

In sectoin Advanced ECM Data click on High Pressure Common Rail Setup, and change the code on injector#6.
The bar code is telling ECM ijector flow and timing characteristics to maintain proper fuel/air mix. Wrong code might lead to really bad consequence but might not. Depends how two injectors characteristics are different. Change it ASAP.

What are your thoughts on changing the fuel connector along with a new injector? I noticed the book mandates this, but of course I didn't find out until everything's tore apart.

The fuel connector tip mates and is literally crushed/deformed to the injector to hold back the 40,000+ PSI of fuel pressure. That is its seal, because no o-ring would hold that kind of pressure back. - Replacing it is a MUST if you want to ensure you don't get an internal leak.
Fuel connector needs to be replaced when...
- If the injector is replaced.
- If the head is replaced, then all 6 of the fuel connectors need replacing.
- If an injector is moved to another location on the head.
- If it has been removed more than a couple times.
It is also important to torque them properly and to spec.

When my truck said injector spill valve I reaplaced my 3 cylinder fuel pump to the 2 cylinder with upgraded parts and code went away. I had no surge. When I did get a surge 1 year later I had air in my fuel system. The fuel tank tubes had a crack and causing a big surge here and there untill I started loosing power. You can check the fuel pressure on insite see if it stays up and go from there.

So I looked in my eyes and I noticed that none of my injectors have barcodes. Almost like someone reset all of them and left it.

If it was my truck truck I will go back and pull all the injectors 1 by 1 and write them on a paper and then go back to insite and correct the missing info.

Yeah that seems to be the next move

You don't need to pull out the injectors. All you need is a small mirror and some patients and you can read them in place.
