am using 60's on my forged 347 ,AFR and F1R making 15 psi..using bosch inline fuel pump works with boost..my fuel pressure stays constant @54 PSI the FRP doesn't increase the fuel pressure under boost although it's a boost refrenced..the car made 670 with 120% duty cycle do i need to change the regulator ?

If your fuel reg is boost referenced, then it should be raising your fuel pressure 1 to 1 with boost. Some thing isn't right. You will get more out of the injectors if the pressure is higher. Your fuel pressure should be 58psi at idle with the ref line disconnected and then raise from there with boost.
we did 442 hp with 1.07 litre 4 cyl and 8- 42 lb injectors
