A bit of a mystery about a set of four 1.8L injectors compared to known info. Known is VW/Bosch part 022906301C/0028150112, with spec of 18.1 lbs/hr or 190.2 cc/min. See top of pic (blue module).
This other set (bottom of pic gray module) has same VW number but has Bosch number 0028150102 (not 112); Mr Injector test results show 200 cc/min. Looks same as known. Can find no reference for a Bosch injector ending in 102.
Questions: 1. Might the second set just be stamped wrong or are older, being superseded by 112?
2. Any undesirable or unwanted results from flow slightly higher than spec? Would it run rich?
Way out of my wheelhouse here, so community experience and wisdom much appreciated!

These systems aren't measuring resulting mixture at all, hence no O2 sensors. So, it will inject fuel based on upstream inputs only; no down stream trimming.

Are you thinking about a mix and match set or running all 102 vs 112s?

Van; if I use them I’d use all four matched, tested -102 units. Correct VW part number on them but the variant Bosch number is throwing me. Current ones running ok but the are 50 years old so maybe not as good as they could be. Not an urgent or required changeout, for sure, but would like to confirm to keep for future install.
