You can only use the FMU with factory injectors. The FMU increases fuel pressure as boost increases. It's function is to prevent the need to replace the factory injectors with larger ones.
You can't use larger injectors without some means of tuning for them. Such as the SAFC or a ROM tune from JWT or EFI Specialists.
You can't just install 370cc injectors without a tune or you'll ruin your motor, if it runs at all.
