ThunderMax Performance ECM For Street Models

ThunderMax now supports the full line of fuel injected Harley Davidson models, including the new Street 500 and 750 platforms. ThunderMax uses WaveTune technology to tune over three times faster than any other system available. The use of wide band 18mm O2 sensors gives a 500 times greater reading over the factory narrow band O2 sensors – no dyno tuning required. ThunderMax is not only easy to use and install, the module also increases throttle response and engine performance while creating a smoother and cooler running engine. The ECM automatically tunes for riding style and conditions; such as altitude, barometric pressure, and ambient air temperature. With ThunderMax you will never outgrow your motorcycle.
