All I can find online is it increases voltage to the pump as boost increases. Does the higher voltage make it actually pump more?
As the boost psi comes up the msd box will increase voltage to the pump. Just like a electric motor. More volts you put to it faster it spins. This will also help with loss of volts through the factory wiring goin to the pump. The two long lead wires, (+) (-) runs from the msd box to the pump. Decent size wire too.
