We always recommend flow-matching before delivery. Factory tolerances of the injectors differ, and you have to run them unmatched with wider tolerances or compensate for this when tuning the engine management system. How much they differ from the factory continuously varies. Flow-matching is done with our top equipment when you add this option! In addition, we include documentation and certificates with your new injectors.
