This has been discussed all around the world for many years. The numbers you provided plus in a few conversations other Bosch numbers as well. I have seen where someone has tested at least three of the injectors, 007, 015 and 023 to find the hold, open and flow for each was the same. Say where someone thought the lenghts wer different only to have someone post pictures of them side by side, exactly the same. Some people have written Bosch and got no real answer from them either, just that the numbers match for this or that car. I would say at this point that nobody really knows why the different numbers, maybe just because they were installed in different cars? Oh, the person who did the pressure tests didn't provide the results, just stated they were the same.

sounds like a dead end unless a fortunate person wants to order all 3, run the flow testing, and publish a report

thanks for your info, that helps
