The ThunderMax EFI system is a game-changer for fuel-injected Dyna and Softail models, offering a powerful self-tuning solution that adapts to your specific setup. Whether you are running a stock motor or have upgraded to high-flow pipes and air cleaners, the AutoTune function uses a wide-band, closed-loop system to constantly monitor and adjust air-fuel ratios. This ensures peak performance regardless of temperature or altitude changes. You will notice easier cold starts, a much smoother idle, and crisp throttle response across the rev range. It even helps eliminate that annoying exhaust popping on deceleration. Keep in mind that this system requires 18mm exhaust sensor bungs, so you may need to modify your pipes if they aren't already equipped with the larger bungs used on 2007 to 2009 models.
