Holley has done all of the heavy lifting in putting together these 100% complete systems. Trust me--you can handle it from here.
Are you ready for professional grade vehicle management? I'm talking about controlling fuel and ignition right down to the cylinder level on as many as 10 cylinders. Reading paddle shifters and electronically shifting transmissions. Driving single or even dual drive-by-wire throttle bodies. Controlling boost, injecting water-methanol, and running multiple stages of progressive nitrous--all without add-on controllers. Having up to 79 advanced inputs and outputs at your control. Yeah, that's you. That's Holley Dominator EFI.
We offer two categories of fuel pressure regulators:
