Holley VR-1 pump with MS3 gold box?
Hello folks,
Im doing my first LS powered build and may have made a purchase hastily. I don’t have any experience with MS3 or Holley EFI nor do I have any experience with this fuel pump. My original plan was to use the Holley Dominator but as you may know they aren’t cheap. I found a new VR-1 pump at a good price before buying my computer for the build.
My question is can I run this pump with a MS3 and still have the controllability that I would with the Holley EFI?
Thanks in advance!

Once you add the inputs and outputs to the MS3 to match the Dominator it costs more money. The MS3 has years of programming over the Holley, so it's better other than the 16 bit setup and harder to use. Yes, it should be able to control signal the vr1 controller.
