i am using a blox 12:1 fmu and also have an aem fuel pressure regulator which is set at 45 psi. my question is that since the aem is a 1:1 ratio so for every pound of boost yields a 1 pound increase in fuel pressure; would the blox negate that or would it cause injector problems. stock injectors with 255lph walbro
thanks

anything between the rail and the tank can alter fuel pressure. the location is not really vital. so to answer your question the blox will still raise the pressure as intended. FYI that factory fpr is 1:1 also

Like everyone will say after this tho, it has been proven to not be the most reliable source for extra fuel needed. anything beyond very low boost settings will need a more advanced EFI management

running 8psi. could i run an apexi air fuel controller or something of that nature in conjuction with the fmu?
