Polaris Sportsman 570 Stage 2 kit

The Polaris Sportsman line leaves a lot on the table in performance. Our tuning will open up the throttle, remove the torque limiters, speed limiters, correct fueling and modify timing to maximize power on 91 octane. Along with that we lower fan temps to help keep things cool, and do a bunch of other custom tricks to make your machine perform at it’s best! Our Stage 2 includes your choice of Dynojet Power Vision 3 or 4 tuner, 4 tune stages, custom built clutch kit to your application, and an industry exclusive Dynojet lifetime warranty belt!

With 4+ HP gained at the wheels this kit is sure to turn your Sportsman 570 into a completely different machine.

• 100% Throttle opening in all gears
• Improved throttle response and drivability
• Misfire detection sensitivity reduced to lower the chances of false codes
• Professionally built ignition timing optimized for 91 Octane for maximum reliable power
• Fueling adjusted for aftermarket components (intakes, exhausts) for optimal Air/Fuel Ratios
• No need to run a “piggyback” fuel controller with our re-flash for most bolt on mods
• Torque Limiters removed
• Cooling fan on temperature is lowered. 190 on/185 off. If you have a heater we will supply you 2 files on request. 1 with stock fan temps, the other with lowered temps so you still have maximum heat output in the winter when needed. Although we have not found it necessary to have them with the stock thermostat opening at 180.
• All functions remain intact – Drive modes, turf mode, Descent control, HVAC systems, etc.
• On multi mode units we only tune performance mode leaving the others functioning as designed
• All of our tuning is built in house on our state of the art Dynojet 250iX dyno and real world tested on trails, roads, and race tracks all around the world.

Stage 1 – 91 octane, Stock intake, stock exhaust – 4 whp

Stage 1.5 – 91 octane, Aftermarket intake, stock exhaust – 4 whp

Stage 2 – 91 octane, Stock intake, Aftermarket exhaust – 7 whp

Stage 3 – 91 octane, Aftermarket intake and exhaust – 7 whp

When selection options, tire size is “effective” taking into account gear reductions, portals, etc. that get you back closer to stock sizes, not “actual” size.

An intake modification would be something like a snorkel kit, not an air filter.

If you have an aftermarket exhaust, please note what it is when checking out so we will be able to match your tunes to it.

The tuner ships blank and will require a windows computer to email in for activation once received.
