    I'm sure it could be done but really isn't necessary or even needed with just a d-plate. There would be no measurable performance gain. When we raise the compression, advance the timing or have these engines ported is when more fuel is really needed. At that point an EFI controller is usually added or some send the ECU out for reprogramming. It's only really huge and modified engines that need an adjustable regulator with a return line...and there are ways to even get around that these days.
