What exactly does bosch or gm do to the ' updated ' injectors ??

There's really no way to tell the difference just by looking at them. And honestly I've never gotten a good answer about what the differences are. I've talked to several people with GM and DDP but no one's really been able to tell me what the diffs are. They're probly all the same, with an "updated" part #.

I couldn't figure it out either, I did have a green mark on top of the new GM remans that I put in and the old ones had white marks on the top of the black plastic piece. Wish we could find out which ones are which so that I have an idea of what they are.

GM will NEVER tell you that. All they say is that they have been redesigned.
