Here you can purchase multiple LaRue tunes for a Polaris RZR Pro R 4 cylinder. You can add these tunes with a LaRue RTD Flash Device to your Pro R that has our Turbo Kit. (device not included) RTD is a tune delivery device. It allows customers to send vehicle read files and share data logs directly to their tuner and receive professional calibration and files to flash to their vehicle via the TDN App. This device gives the customer options to change between tunes with their stock ECU. The RTD offers full iOS and Android support with the TDN App. Tune Delivery Network (TDN) is the new standard for remote tune delivery. It's a free-to-download TDN app available for iOS and Android. The TDN app syncs with the RTD device via Bluetooth, removing the laptop from the equation when licensing and writing tunes to your vehicle.
