a true rising rate regulator has a adjustable fuel slope so the ratio can be changed from 1:1 all the way up to 14:1 ... such as a BEGi MR2035
a 1:1 regulator is only useful if you are running massive boost pressures that are effectively counteracting your fuel pressures reducing the injectors spray volume and are using another module that allows you to tune the injector pulsewidth. this makes the 1:1 regulator maintain the injector spray volume at lets say 2ms at 0 psi intake manifold pressure the same as at 20 psi intake manifold pressure. without the 1:1 volume sprayed would be reduced greatly at 20psi as the fuel pressure would be effectively counter acted by that amount.
adjustable rate, rising rate regulator has never been my way to go about things as i prefer the accuracy of the auxillary injector but it will work
