WSRD Tune Features: 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!
