I have a 69 dart swinger with a built 318. When I hooked up my msd 6al the car would surge under light acceleration, but run like crazy when I put my foot in it... Unhooked my msd and it runs fine,,, no surging... I'm putting a 340 in my car in the spring and I would like to run my msd. So if anyone might be able to tell me what might fix my problem that would be awesome...:banghead:
