Precise Tuning: Leveraging existing fuel injectors for meticulous air-fuel regulation

The FPD-R (Fuel Pulse Damper-Range) and FPD-XR (Fuel Pulse Damper-Extra Range) both have unique base "static" fuel pressure requirements:FPD-R base pressure requirement = 40 - 70psi (static)FPD-XR base pressure requirement = 40 - 105psi (static)Base pressure is the fuel pressure measured when the fuel pump is running WITHOUT a vacuum line connected to the regulator
