The RZR Trail S 900 has the wider stance and longer-travel suspension to handle faster trails, and it deserves a tune that lets the engine keep up. The Dynojet Power Vision 3 releases hidden power and improves overall performance. It modifies engine timing for more horsepower and raises the speed and rev limiters for higher top speeds. It also works as a diagnostic tool and lets you tweak your own tunes. It plugs into the diagnostic port, and installation takes minutes.
Performance Changes
- More horsepower from adjusted engine timing.
- Raised speed and rev limiters so the Trail S can use its suspension on faster ground.
- Left-foot braking for steadier control through whoops, berms and descents.
- Faster limp mode to get back to the truck if something goes wrong.
- Lower fan temps for a cooler-running engine in slow sections.
- Stock settings saved so you can flash back at any time.
Easy Install, Useful Data
Power Vision 3 has a bright, full-color screen that's easy to navigate. Installing the tune takes only a few minutes. Once it's installed, keep the tuner plugged in for a live view of RPM, coolant temperature, wheel speed and more. It logs that data so you can upload it to your PC and review it with the included Power Core tuning software. Use the logs to troubleshoot issues or tweak your tune after adding parts like a clutch kit or exhaust.
Built for Faster Trails
The Trail S 900's extra width and travel let it run faster through rough terrain than the standard Trail 900. With the factory limiters raised and timing improved, the engine finally matches the chassis. You'll feel it in every pull out of a corner, and the higher top speed gives you more room on wide-open two-tracks.
Keep an Eye on It
Because the Trail S 900 encourages faster riding, the live coolant temperature and RPM readings are worth watching, especially on long, hot climbs or in deep sand. The data log gives you a clear picture of how the engine handled the day, so you can spot trouble before it becomes a breakdown. It's a simple habit that keeps a tuned machine healthy for years.
