The Polaris RZR XP Turbo is an amazing machine right out of the box, however, it's capable of so much more! We extracted another 20 rear wheel horsepower out of the RZR XP Turbo using HP Tuners software and the Remote Tuning Device. Take your RZR XP Turbo to the next level with the Stealth Performance tune! In addition to more horsepower, you also will experience an additional 9 lb-ft of torque as well as a "linear" throttle response. This means if you give the RZR 70% pedal, you'll get 70% throttle. This results in a much more responsive feel and more fun when ripping up the dunes, trails, dirt drags, and more.
If you are on 91 octane fuel and would prefer a bit more tame tune, then we have the Level 1 tune available as well which adds 14 horsepower. Or, maybe you would prefer a less aggressive tune for trail riding, the Level 1 tune makes a great option with a little less throttle response and boost but still a lot of fun. You can also elect to have both and switch between them from your TDN app on your phone.
An RTD is a "remote tuning device". Simply put, this device allows us to easily send our tunes over to you. Even more than that, it allows you to data log after our tune is installed to make sure everything is good to go!
A tune, otherwise known as calibration, is a file written to the computer in your vehicle that runs your engine. This control module is sometimes referred to as the Engine Control Module (ECM), Power Control Module (PCM), or Engine Control Unit (ECU).
The tuning process will void the factory warranty related to that modification. For example, if your windows stopped rolling up, this should still be covered since it is not controlled by the ECM.
