Whether you’re looking for more fun, or just leave your friends in the dust. You need this tuning. If you are like us we were pretty disappointed in the 570 engine platform from Polaris. Overheating is common, along with melted plastic if you use it for any type of work around the farm or ranch. We just thought that engine was designed wrong because it runs so poorly from the factory always sputtering and popping. We also found that it was near impossible to keep a consistent ground speed when used for spraying or pulling an implement, the engine constantly would hunt and change rpm as if it did not have enough power to do the job. MTNTK Performance has developed a new performance tune using the DynoJet PV3 that reduces the restrictions in the ECU for a Polaris Sportsman 570 and wow IT RUNS SO MUCH BETTER! Tuning this engine makes it run smoother, cooler and is much easier and more enjoyable to drive. The installation of the MTNTK Performance tune, using the DynoJet PV3, raises the rev limiter, and increases power substantially. It also gives you better throttle response. Each tune is specific for your Polaris Sportsman 570 ECU. Fuel and timing adjustments are made to allow the best performance upgrade that is possible without making serious modifications or using special fuel. With the use of the DynoJet you can tune your Sportsman, log your engine data, and monitor your performance. Monitor your Polaris Sportsman 570 performance in real time and eliminate the cost of a service appointment just to read a code. You can check the code yourself through the DynoJet tuner and determine what, if anything, is needed on your Polaris Sportsman 570. This DynoJet tuner allows you to not only monitor your Sportsman's performance, but also logs your engine data! It records 20 minutes of performance and gives you the option to playback the information that is relayed to your ECU when it is convenient for you. For the Polaris Sportsman 570 applications, the tuner comes with a preinstalled tune and is easy to update as upgrades become available. No hassle of shipping ECU or tuner back and forth to MTNTK Performance for updates. It has internal memory that can be updated from the comfort of your own computer by having MTNTK Performance email you a new tune when necessary.
