I have started to watch how I start my 911 now that I have the 3 second prime version of the DME. I have to deliberately pause to hear the pump run if I want to hear it. When I forget and just start the car normally, it is just twist the key and there might be a 1/10 of a second of extra prime if that. And the fuel system has a return line and the injectors don't fire unless the engine is rotating. There is no reason to not get the pump prime model.
