Injector Balance/Trim Range

[Gary]

Does anybody happen to know what are the specs for the injectors on a 6.4? I’m seeing 12 to -7, I don’t think they are supposed to be that far apart. Also getting a P088 code.

Too much variance. How's blowby?

Next step is compression test.

Ford told me at one time there isn’t really a spec, but +/- 10 is typically what they go off of

No blowby.
It runs good, it’s setting a P0088, so the first thing I did was check the injector data

I had a fairly new injector get to 12, I noticed a difference in mile/tank and on a tank and investigated as i usually did within 15 mi per tank every time. Sent that injector back in (30%) they confirmed an issue and sent another new one. My wife myself and son all drive diesels (VW/Audi ftw) and I swear by setting trip every tank. Typically if one of the cars loses 20 miles on a tank for no other reason a fuel filter swap gets it back on track.

+/- 9 is within range but I don’t accept anything in the 8’s. Mine is currently cold start-7 on cylinder 5 after warm up everything stays around -3
