jecs 550cc injectors on 555cc ecu upgrade??

[DevZX]

Hey guys i got a ecu upgrade from z1 set up for 555cc injectors now would running jecs 550cc injectors be a problem?? Technically it would run alittle lean right? But would it be significant enough to make a dofference? Thanks

If memory serves me right, the JECS injectors are re-drilled and are likely to have more than a 1% flow variation, if I were you I'd have them flow tested before throwing them in and contact Z1 to see if they'll work.
