It sounds like you have made some modifications to your Ursus C-360 4x4 tractor in FS25. Adding GPS, a ledbar, a tuz (front weight), turbo, and a button box can enhance the functionality and appearance of your tractor. The GPS system can help improve precision in tasks like planting and harvesting, while the ledbar can provide extra visibility during low-light conditions. The tuz can help with stability and traction, especially when using heavy implements.
The turbo addition is particularly interesting as it can significantly increase the engine's power output, allowing for improved performance and efficiency. However, it's important to ensure that the engine is properly tuned to handle the increased boost pressure from the turbo to avoid any potential damage.
Lastly, the button box can offer convenient access to various functions and controls in your tractor, making it easier to operate while focusing on your tasks. Overall, these modifications sound like they could enhance your farming experience in the game.
