I was picked to try this on my POTC. It is amazing. I am the original owner of my pirates and have done all my repairs. The most I have done when it comes to soldering is attaching a broken wire. The thought of desoldering/soldering a board pretty much intimidated me. I resigned to either spending $400 or pulling the board and shipping it off. I am so happy that I waited and bought this.
First off, the instructions are spot on. The pictures alone explain everything you need to do. The entire install took less than 10 min. It is as simple as attaching two wires to the board via screw that holds it, replacing two fuses and then securing the caps inside the Blackbox. Really that simple.
As far as performance, it is as great as everyone has said. The flippers are snappy and quick. I had to turn down all the coils, and playing with them now to find the sweet spot. Much easier chest shot, Bayou hole and ramps. Star Map really flings the ball and you can tell the magnet grabbing the balls is stronger.
The Must Have Mods for this game are the Chest mod and the spinning disc belt. Now there is one more and this is it. No matter how you change the caps, this is the easiest.
