It sounds like you have either some plumbing issues, or carburetion issues. You need to first check with Magnafuel to see how they want you to plumb the system. On a roots style supercharger you would not boost reference the fuel pressure regulator since the carburetors are above the supercharger and only see atmospheric pressure. Boost referencing is normally only done on carbureted applications when you vary the incoming air pressure to the carburetor such as in a turbo or centrifugal supercharged application. On an application like this normally you'd like to maintain between 6.5 and 7.5 psi through your entire run.
