Default Acceptable injector balance?

Had my injectors cleaned and balanced after 1year of racing with e85. They all were good except 1 was 4% down from the rest. Anyone have real world experience with a 4% off injector? They are bosh 80 pph.

There is no PW given in the report. It shows ohms and pressure. I assume they test at full voltage and don't use pulse width when flow test.

they should test at a specific PW for the whole test.

i.e 5.6 ms PW

If tested static, the test is almost pointless. You would or should never be running the injectors in that state.

Ok let's say it was tested at 80% pw. Not sure what 100% pw is but just shitz and giggles. These injectors spend most of time in the 80% duty cycle. It's a track only setup. I am gonna run it and check plugs, but I can add 4% in the Holley ecu.

Well obviously if you know the results of a dynamic test, then you can trim individual cylinders via the ecu....then the original question is null and void.

4% is not acceptable.

Static Testing and Dynamic Flow Balance Testing should both be on the flow report imo.
