How can I get more fuel to build up boost? I am trying to understand pw duration right now but am confused because at a given fp and mm3 it is just the time the injector is open so how does it effect the amount of fuel if it is always gonna be the same amount. Like if I add a high duration certain mm3 will that increase the amount of fuel? If you decrease fp it will require the injector to stay open longer to reach the necessary mm3.
