I'm thinking on running a safc , but don't know if i need to run a fmu with it. I'm only running 5-6 pounds of boost and have the 370cc injectors. Not looking for alot of power. Any sugestions?

its up to you on how far you want to take your goals..and cheap or you want to spend..safc's arent really expensive but if you want your goals to end soon then you can go cheap and get a FMU...if you want to move on..go with a SAFC

FMUs (or rising rate fuel pressure regulators) are usually used to increase the flow of stock injectors when no mangement is present. Since you plan on using an SAFC to meter fuel, you dont need an FMU.
