Default Fuel Pressure Regulator

Can someone tell me what the importance of buying a bbk fuel pressure regulator is? I've heard they are ideal with larger MAF's and TB's. But what do they do and where would they install to? Thx

thhe AFPR is used to increade or decrease the amount of fuel pressure in the fuel lines the more pressure the more richer it will run and the lower the leaner the car will run you put this one when you do your h/c/i bc you will need more fuel bc of the increased air flow. That is also why we recommend changing the injectors to 24's at the same time as the h/c/i
