For Milwaukee Eight Softail from 2025 onwards

• The ThunderMax EFI system with AutoTune is built for uncompromising performance.
• It works on any bike, whether it's an unmodified bike, has a performance exhaust, and/or performance air filter, or any other performance modification installed.
• The ThunderMax's AutoTune feature will continuously tune any fuel-injected Harley engine for maximum performance.
• This is a closed-loop wideband system, meaning it continuously and automatically adjusts air/fuel ratios every time you ride, regardless of changes in the bike or any environmental conditions such as temperature, barometric pressure, humidity, or a change in fuel quality.
• Once installed, the ThunderMax with AutoTune precisely adjusts your base map to your riding conditions and habits, automatically, every time you ride.
• With the ThunderMax, you'll experience easier starting, a smoother engine, crisper and improved throttle response, greater performance at all riding levels without sacrificing fuel economy.
• You'll also eliminate exhaust popping, spitting, and backfiring for better sound.
• The ThunderMax is an industry award-winning product that outperforms all other tuning systems in all riding and performance categories and comes with a 3-year limited warranty.
• Note: ThunderMax installation requires an exhaust with inlets for 18mm exhaust sensors as used on 2007-2009 models, or modification of the original exhausts to accept 18mm O2 sensors.
