Fuel injector flow rate

Wow…. Ok. Thanks Tony.
Any guess in why the change in AFR?

Manufacturing differences / tolerances ? How the testing equipment was calibrated maybe . If you took 20 Bosch injectors and tested them you would probably find a spread ? This is not something to worry too much about . It’s just something to be aware of. If you were inclined you could have the injectors tested first and compare the results . I didn’t do this either. I have a Dynojet PCV installed and the dyno shop tuned them with that.

Just found my box of Norton bits while rooting around and found my old injectors but also the short adapter leads I had to use with the new ones... Forgot about those. Different connector on the new higher rate injectors. Can't remember for the life of me the connector codes.....

Thanks for the info. I think I’ve seen those adaptor wire plugs. Hopefully my new ones are the ev1(?) like the originals.
