Want your Jersey Jack Pinball Slingshot to have more power? This mod will do exactly that!!! Here is a video showing it working on default slingshot power in the menu so you can go higher but I did adjust it to be set at default setting. Very easy install just desolder slingshot wires and put module in the circuit. Input is the wires from the game output to the coil. Kit comes with two black boxes to do two slingshot.
