if you run low psi then you might just need a fuel pump and an fmu. a step up from the fmu and fuel pump would be the fuel pump, injectors and an afc. on this setup you can run 10lbs fairly safely as long as you get it proffessionally tuned. a step further would be hondata s200b, fuel pump, injectors, and a good tuning. if you want to go all out then get an aem ems or another standalone system.
