Thread: Scaling back injectors

    Scaling back injectors

    Running through a tune from a tuner and noticed the injectors look to be scaled back. Though its more injector than the car currently needs. Just curious why scale them back vs adjust the tune elsewhere. Any reasoning why?

    Depending on how much head room the vehicle has being turbo, whipple, procharger, the tuner might have scaled the MAF, when doing that most not all tuners will scale injector and engine displacement and manifold volume to match the scaling. The other reason might be they only scaled the injector data to achieve certain fuel trim.
