Fueling boxes well obviously add more power by adding more fuel ? Timing boxes are the real mystery to me. People talk about adding more timing and having too much timing can blow your head gasket... Do they mean injection timing advance and more or less advance? Does timing add power ? or does it change the power characteristic of the engine? I thought the VP44 was geared and timed with the engine so how does it change the injection timing?

Not sure if anyone can answer this but i would like to have a better idea whats going in my engine/VP44
