I just baught the B&M Commandflo fuel pressure modifier. People have told me the Aeromotive AFPR is way better. Also I heard you can only increase the fuel pressure. Do they mean once you increase the pressure higher than stock you cant go down or you can't lower the pressure more than stock. Which fuel pressure regulator do you think is better?

 

You cant lower fuel pressure any lower than stock, which doesnt really matter cuz the reason you need it is to raise the pressure at idle. But i dont know anything about which is better. I would have to read into them
