Will upgradind fuel injectors to higher CC increase performance in any way? Or what difference would it make?

with upgrading injectors gotta get a retune to account for the extra fuel. It depends what you are running really from upgraded internals to boost.

Once you get bigger injectors stock ECU cant really account for the extra fuel coming so your engine may end up running weird. Something such as a piggyback like emanage to properly adjust air/fuel ratios and such to get proper gains from bigger injectors.

yeah mte you'll definately need a retune or at least a safc like previously stated. i ended up putting 7m injectors in my 4afe, without my safc my car would have never ran. before i used my apexi safc to lean it out -15% or more. before i did that the car would turn on, but it would turn on very rough and after a couple of seconds since there was too much gas it would flood the engine and turn off

Gotta have mods that can support it, but imo it isnt needed unless you going boost or building a fully built NA motor.
