About this part

Product Details

The TFI (Throttle and Fuel Injection) Power Box from Big Gun is built with third-generation technology to help your Can-Am Defender HD8 or HD10 run better, especially when you've added an aftermarket exhaust. It works by fine-tuning how your engine's Electronic Fuel Injection (EFI) system talks to the throttle, making the connection feel more direct and responsive. This means you get a sharper throttle response and a smoother build of power, particularly in the mid-range where you often need it most for work or play.

Installation is straightforward thanks to its plug-and-play design, meaning it connects directly into your existing EFI system without altering the stock ECU map, so reliability isn't compromised. You can make adjustments on the fly using the integrated faceplate buttons, and you won't need a computer to dial it in. The unit itself is well-built with rugged construction and weather-resistant sealing, ready to handle the tough conditions your Defender might encounter.

This Power Box is highly recommended if you've upgraded your Defender's exhaust system, as it helps optimize the entire package. It installs in minutes, giving you an improved performance feel without complex modifications.
