If they don't peak together, you can try swapping injectors around.
It's not strictly legal - but it's not actually illegal either. There
is no requirement to keep track of which injector goes to which jug
when they're cleaned, since in theory they are all the same diameter.
In practice the published tolerances are ridiculously wide, and half of
them don't meet spec anyway, but let's not confuse the issue with the
facts. If you "accidentally" got them reversed next time they were
cleaned, well, these things happen.

That used to happen a lot on my engines, until they strated running LOP
smoothly. Ever since then, I've kept track of which injector goes to
which jug. No rule against that either, you know.

Let me understand this: you achieved smooth LOP operation by playing
"musical injectors"?
