If you want to do the FMU thing, get a 6:1 calibration disc setup for it, which is the correct calibration for your injectors.
30# injectors: FMU w/ 6:1 calibration discs, fuel pressure vac off 40-42+ psi (depending on how much your car likes/disklikes fuel pressure)
12:1 FMU w/ 30# injectors = soon to have a very light wallet :(
