The Greddy controller has a map sensor so you can pulse the injector as the boost rises, very tunable. I use a fuel pressure gauge on the control pressure and a wide band O2 sensor to tune with. You can run your fuel distributor at max flow if needed.
It is exactly like the frequency valve. Might even be able to control a stock valve with a controller like this.
