Did yours become more obvious over time?
Thank you. I will look at DI as well.

ok i had experience on this issue , and i had replace 8 direct injectors until now
so to be sure about your injectors try to log the LTFT . normally it should be 0% to 8% max . in mine it jump up to 35% . it means my injector had short delay then what is should delay it .
but it is so hard to test which one is bad injector so Subaru recommended replace DI as a set
it is with ***j700j rom
as fa20a works with dual injectors per cylinder .so there are special timing for each injectors in one cylinder . from the logs the DI controlled for 2500RPM to 5000RPM
Did yours become more obvious over time?
yes it will be worst become bad injector shorter and shorter. LTFT will insurance but if your are with ***j700j or ja01j it will not throw cel about system leans coz the rom not include it
there are to kind of dmg with DI as i known the burn DI seal and it will throw pressure leaks in the cylinder and DI lost delay time without codes .
