with dsm injectors and an inline fuel pump will i need a fpr to reduce fuel pressure so my idle wont suffer? i've got a d16z6 and will be getting a vafc with the turbo. can the vafc control everything or will a fpr be needed?

 

I believe that the VAFC can control everything. I have an FPR and will probably keep it to reduce pressure even a hair below stock. I realize that you have to have a certain pressure in order to get proper dispersion, but a little lower will only help the pump flow more.
