No a 1:1 FPR will not work for your application. Yes you can dial down the fuel pressure and get the car to run at idle and in vac. But as soon as you boost you will lean out just like you are running stock injectors. You would need some way to tune the injectors to provide more fuel. IE Megasquirt. Or you can run the SFMU and use fuel pressure to inject more fuel.

Your SAFC is not powerful enough to control injectors that large, but you could run the SFMU and make small adjustments with the SAFC to dial in the A/F ratio
