Lights flicker and gauge jumps around???

Great thread. Help me out though, I have installed HEI on my slant, so the ballast is gone. I have also installed a relay for the ignition, and done the MAD bypass. Is your relay something different that the ingition relay? I also already have a relay on the HEI, and also a pair of relays on the headlights. I still have real bad light flicker/pulse.. all the time. If I speed up , the flicker speeds up
