    fuel regulator vs diff inj

    What is the difference between stock inj plus rude fuel regulator vs changing inj? Both using stock ecu( can i change inj with a stock ecu? Isn't each stock for particular inj?)

    As far as performance , stability engine and fuel consumption?( what is the increase of fuel consumption chsnging inj from 42 to 50?)

    RRFPR will change the fuel pressure. What are you doing that you need to know

    rrfpr will allow a cleaner leaner idle while still adding additional fuel for mid and wot and also gives you adjustability. Depending on your set-up you may need both larger injectors and rrfpr as the rrfpr will only do so much. You can run larger injectors with stock ecu but without rrfpr it will be richer at idle.

    That pretty much sums it up
