Any time you improve and increase air flow in your engine, whether through intake or exhaust improvements, you likely will also need to increase fuel flow. Our Adjustable Fuel Pressure Regulators give you the easy ability to tune your cars fuel pressure to fit the modifications you've made. Computer chips can control the pulse action of the injectors but only an adjustable fuel pressure regulator can regulate the volume of fuel going to the injectors.
