The pump features about 20% more flow over our existing industry leading 200 bar pump, the FX200. The pump is completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAre tune changes required?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cstrong\u003eThe upgraded pump does require calibration changes.

Custom tuning is required to get maximum output out of the upgraded pump setup for your specific vehicle setup and ambient conditions. Spool Performance is a hardware manufacturer and does not provide custom tunes, but can assist with questions your tuner may have.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cstrong\u003eLow Pressure Fuel Pump Upgrade:\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eProper low pressure fueling is extremely important for proper functioning and durability of the high pressure pumps and injectors in a DI system. Inadequate low pressure fueling can cause damage to the pump piston and bore as they are lubricated by controlled leakage of fuel. Resulting damage from low pressure starvation is detectable and would be cause for voided warranties. Please make sure you plan out your fuel system build with proper low pressure upgrades when necessary.\u003c\/p\u003e\u003ch3\u003eAvailability and delivery\u003c\/h3\u003e\u003cp\u003eSupplied to order.
