In general injectors are not flow matched unless specified. It's a Racing industry standard. let alone oem vehicle dont even come with flow match. if you pay attention in bone stock vehicles, at idle you will notice dips/ rises continuously but every so slightly. thats for the inconsistency in the injectors. flow matched makes a huge difference!

you can contact the closest Unitronic Dealer as most performance shops can offer this as an additional service.

Not to mention cylinders will run slightly rich/lean, not a big deal with factory horsepower but can become an issue with big power.

Flow matching is typically an additional cost service.
