Ok so here it goes. I bought a vortech v3 supercharger and my engine is not stock it is a stroked 347, trick flow heads, intake, 24 lbs injectors, and larger fuel rail. My question is do I have to use the vortechs FMU or can I just keep what I have. Until I save up and switch to 40lb injectors and larger pump? Confused

Well likely you will not be able to keep what you have. If you have a boost referenced fuel pressure regulator you may be able to but I have to stress may. It could quite possibly be too lean and that would be a very bad thing. You are probably better off using it for the time being until you get bigger injectors and new computer programming.
