Power Output:  2016 Polaris Tune: 144 Crank Horsepower WSRD WS140 Tune: ~156 Crank Horsepower Boost Pressure: 16 PSI Please Adjust Crack Pressure to 5 PSI 2017+ Polaris Tune: 168 Crank Horsepower WSRD WS170 Tune: ~190 Crank Horsepower Boost Pressure: 17-17.5 PSI | 91 Octane Boost Pressure: 18 PSI | 93 Octane Please Adjust Crack Pressure to 6 PSI WSRD WS190 Tune: 195 Wheel Horsepower |~ 218 Crank Horsepower Boost Pressure: 20 PSI | 98+ Octane Please Adjust Crack Pressure to 6 PSI WS140 Tune Features: Boost pressures are increase up to 16 PSI respectively for the octane you choose to run. Crack pressure set to 5 PSI Radiator fan activation temp lowered from ~200* F to ~175* F Torque limits for L raised to 100%, reverse raised to 75% Component protection mode for fueling lowered to increase torque and horsepower, especially right after the pedal is floored.  Ignition timing per cylinder is optimized for maximum power as well as drive-ability, careful consideration was used not only for when at wide open throttle, but as well as cruise, throttle transitions, ect. Throttle feel and control is thoughtfully improved, to control through a whoop section, on/off feel in short course style racing or playing in the woods, eco mode is improved but offers the less aggressive pedal for technical rock sections or simply loading on a trailer.  Speed limits removed, your speed limit is your rev limiter/gear Rev limiter raised to 9200 RPM Rough road detection is raised to max to prevent power loss. Plus more! WS170 Tune Features: Boost pressures are increase up to 17-18 PSI respectively for the octane you choose to run. Crack pressure set to 6 PSI Radiator fan activation temp lowered from ~200* F to ~175* F Torque limits for L raised to 100%, reverse raised to 75% Component protection mode for fueling lowered to increase torque and horsepower, especially right after the pedal is floored.  Ignition timing per cylinder is optimized for maximum power as well as drive-ability, careful consideration was used not only for when at wide open throttle, but as well as cruise, throttle transitions, ect.
