    12-3000-2 VR2 Pump Issue

    Has anyone had an issue with the controllers on this dual setup? Mine seems to be stuck at 50% and have made numerous calls, and even a email to Holley tech and they haven't found anyone that can assist with the issue or a way to test the controllers. I see there's a way to check the firmware and their is a revision, but it does not tell how to do the update. Is there another controller to control these pumps? Running a 16V system.
