In your guys opinions, its a adjustable fuel pressure regulator a cheap, or poor mans version of a Electronic air fuel controller? Your comments please

 

Depends how much fuel you need. The S-AFC and V-AFC seem to excel at taking fuel away from the mix, but not very consistant on adding fuel. Usually both together make a good team. Add fuel with the FPR and fine tune with the AFC...

hmmm interesting. YOu have any or heard any comments about HKS's AFC unit?

 

I have heard about it from some Eclipse owners, and they are not too happy with it. They keep selling them and going to the S-AFC from APEXi...

hmm so what is the stock fuel pressure usually set at and what is the limit of the stock regulator?

 

Depends what car you have as to what the pressure is at. As for max pressure, that depends on the fuel pump and its ability to keep up.
Stock regulator, it is not adjustable, so you have to replace it with an AEM unit, or but it and add the B&M unit. If that is a consideration, I suggest the AEM unit.
