Dear Scoobynet'ers,
From reading various posts a popular mod to increase fuel pressure is the replacement uprated Walboro fuel pumps.
A quick technical question ... if you get a higher flow fuel pump surely this alone will not deliver more fuel? I fully understand that the more pressure at the injectors the more fuel will flow for the same duty cycle.
My theory:

My theory:
- If you are still using the standard OEM fuel pressure regulator then surely that is what is controlling the fuel pressure 'seen' by the injectors?
- Let's say you uprate the fuel pressure regulator, would the ECU not compensate as it monitors the fueling? Perhaps the answer is different when the ECU is in closed or open-loop mode?
Cheers,
