I am working on a turbo setup now and was wondering, when running low boost 7-10 psi should I run injectors, fuel pump, missing link, and fmu?

or can I just run the blue box, injectors, pump?

anyone?

FMU is for use with stock injectors, it has no way of changing injector duty cycle, so you shouldn't run bigger injectors with it. FMU may work well at 7 PSI, but will not be able to raise your fuel pressure enough to run 10 PSI, even with an aftermarket fuel pump.

I'm not familiar with the blue box, but if you have a standalone or piggyback that will control injector duty cycle (V-AFC or Hondata/Uberdata/AEM), then you can run bigger injectors and boost to 10 PSI or more.

if ur running the fmu, i would not go past 6psi

so with the greddy blue box what is the max psi I can run?

youll get different answer, but from my personal experience, i never had issues running 10lbs. i never wanted to boost more then that cause i was already killing the duty cycle on the 310's at 10lbs.
