This increase in pressure, following the physics equation Q=PxA (where Q is flow rate, P is the change in pressure, and A is the area of the injector nozzles), results in a higher flow rate through the injectors, ensuring more fuel is available for combustion, crucial for high-performance applications. The FX350 makes your injectors flow 40% more fuel before maxing out the injection window limitations. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImproved Fuel Atomization\u003c\/strong\u003e: The higher pressure of the FX-350 aids in better atomization of fuel.
