the fuel pressure? if so how does the ecu control fuel pressure in this case. I thought a stock regulator is fixed. I understand its affected by vacuum and don’t regulators have ratios such as stock which i thought was 1:1.

I understand there is such things as a RRFPR (rising rate fuel pressure regulator). And electronic ones out there. But isn’t the typical aftermarket SR aftermarket still 1:1 but instead of 36psi u can change it to 40psi

he said its how u make the car rich or lean… i was referring to that.
