300d turbo up pump upgrade to electric

Hello

Just wondering if anyone has had any improvements in fuel output and power by changing the mechanical up pump for an electronic fuel pump with fuel pressure reg on the returns of the injectors?

I have an aus 300d om603 with a turbo fitted.i have a usa turbo ip pump with boost compensation. My pumps tuned to deliver max fuel and rack but still running stand elements.

I totally under how the pump works so i dont need to be told i need bigger elements. I v just seen a few people with worked pumps run electric fuel pumps.

My car last ran
740nm (1000 rpm )and 105hp at the wheels
450°egt with hardly any smoke.
11° pump timing
Cracked inlet manifold at the time
Still pushed 25-30psi.
