    I have finally completed the testing and now have 3 different regulator springs available.
    A stock replacement spring that will give 11-14psi
    An upgrade spring that will allow 15-20psi
    And a max flow spring to provide late model 454 flow from the smaller more common injectors. 28-34psi

    See the Parts required thread in the injection forum to see how pressure effects your injector flow!

    See the Hamilton Fuel Injection Parts and Service thread above for prices.
