All Dyno results shown were run with 92 octane premium unleaded fuel, expect 1-3 less HP with our 87 Octane developed tunes. We have developed a wide range of tuning choices for you with several customization options. So you can imagine that having the throttle blade open all the way up when you put your foot to the floor will make a big difference in performance! You are guaranteed full throttle with our ECU tunes, no tricks no limits.

A stock RZR 900 with the pedal to the floor will have the throttle blade open around 70% up to about 50mph then that drops down to 55-60% up to 70mph. All torque limitations have been removed so your ECU will no longer 'throttle back' under hard acceleration.

The biggest power increase comes from maintaining wide open throttle at the throttle body when your foot is to the floor. With a 7hp increase on a stock machine and up to a 27% increase for our Stage 3 tune your 900 will keep you smiling. Dyno developed Dyno tested and Dyno Proven, our high performance ECU reflash will make your RZR run hard.
