What injectors do I have?

I have read about BBs and G code injectors, but how do I know what I have got? Mine says:

The injector code should be stamped on one of the flats of the injector that you use the socket or wrench on.

It means that it ain't no BB or G or E Lol, the difference supposedly is in the pop-pressure, also G-codes are considered "emissions" injectors as their nozzles sit slightly higher up in the chambers which apparently is not optimal for performance but somehow help lower emissions?

What are the diffrent injectors for?

I know what Gs and Es are for, but what about BBs, Ds and any other they may have made?
Both me and Joe have BBs in our trucks, and I have Ds on the shelf.

You know what E-code injectors are for? What's their purpose? Emissions? That's what's in my IDI. I bought a set of BB-code injectors and they're waiting to be installed. I'm not sure about D-code.

Ya know, I think I got it wrong - I think it was the E-codes that were emissions, and the G-code are the turbo-specific injectors...

BBs are very popular for turbo engines too, at least among those folks who actually care to replace their injectors when needed. I know they can be shimmed for different pop-pressure, Dyoung (the guy with the 4400 rpm engine) has a set adjusted at 2200psi IIRC, so maybe the codes are just a designation for distinguishing the different pop-pressures at the factory? Well with the exception of the E-codes cause of their different fitment.

Could be just the injectors are tired, regardless of what code they are...
