Big Gun 11-13 Arctic Cat 425 Power Box

This is the Big Gun TFI Power Box for your 2011-2013 Arctic Cat 425. It's designed to give your ATV a noticeable performance boost by fine-tuning how the engine handles throttle input and fuel delivery. If you've added an aftermarket exhaust, this box is a great way to make sure your EFI system is working with it for the best results.

What this box does is essentially remap your throttle and fuel settings to be more responsive. You'll notice quicker throttle response, a smoother flow of power, especially in the mid-range where you often need it most, and a bit more horsepower. It's built tough with weather-resistant sealing, so it can handle the kind of conditions you'd expect to ride in. Plus, it's a plug-and-play unit, meaning it connects directly into your existing wiring without needing to reprogram your stock ECU, and you can make adjustments right on the faceplate without needing a computer.

Installation is straightforward and usually takes just a few minutes. It's a solid option for getting more out of your Arctic Cat 425, especially if you've already upgraded the exhaust system.
