This Straightline Performance tune and DynoJet Power Vision 3 tuner package is built for 2017-2024 Polaris Sportsman 450 and 570 ATVs. The tune removes the rev and speed limiters, lowers fan temperatures, and optimizes fueling, while the Power Vision 3 lets you flash your ECU from anywhere and then stay mounted as a full-color diagnostic instrument panel.

You can quickly build your own tune or choose from trusted DynoJet-engineered tunes, and the included Power Core software connects dyno runs with the EFI tuner. The unit is weather and shock resistant, comes with a one-year warranty and unlimited tech support, and is proudly made in the USA.
