The injectors are configured as a drop-in physical and electrical fit for the supported factory fuel rail, intake manifold, and wiring-harness arrangement.\u003c\/p\u003e\n\u003cp\u003eEach injector flows approximately 1000 cc\/min at 43.5 psi and 1040 cc\/min at the GM original-equipment fuel pressure of 58 psi. This provides substantial fuel capacity for forced-induction, E85, and other high-output combinations while retaining the short-pulse control and characterization required for stable idle and part-throttle operation.\u003c\/p\u003e\n\u003cp\u003eFuel Injector Clinic individually serial-numbers and tests each injector using its Data Match Technology process.
