The Dynojet Power Vision 4 is a Bluetooth flash tuner that pairs with the Dynojet mobile app to write performance tunes directly to your bike's ECU. Unlike piggyback tuners, the PV4 modifies the factory ECU calibration — improving throttle response, removing speed limiters, and enabling tunes built for aftermarket exhaust and intake configurations. This version covers Twin Cam and Milwaukee-Eight Touring and Softail models from 2011 to 2020. The original factory tune is backed up and can be restored at any time, returning the bike to stock.
