I pretty sure the cams play a key role in determining this along with volume of air. Lots of underdrive on supercharger and larger cold air intake require larger than 30# factory injectors. For proper fuel to air ratio. My opinion.
I made my way to all parts houses. Found some that were made with the small ground wire and also the positive post had little wire made into it for a hot to radio or whatever. Been a while can't remember were I got them but they are out there.
Check all vacuum lines and any attachments in vacuum lines running to/from supercharger. May have to remove inner fender well to access all. There is a supercharger air bypass ran with the vacuum.
I'm 41 years old. I bought my first when I was 19. I totaled it. But replaced asap. Totaled one is sitting in the field the replacement is in the garage. Will never sell. Love it.
