Stage 2 – The Ultimate Trail Calibration

270 HP on 91-Octane Pump Gas

The Precision EFI Stage 2 is our most aggressive calibration available while running on 91-octane pump gas.

Producing 270 horsepower, this package transforms your snowmobile into an incredibly fast and responsive machine without sacrificing the reliability that Precision EFI is known for.

Designed specifically for aggressive trail riders, the Stage 2 delivers explosive acceleration, instant throttle response, and relentless pulling power while maintaining smooth, predictable power delivery in every riding condition.

Built for the Trail

Big horsepower is only enjoyable if it's controllable.

During development, our priority wasn't simply producing the highest dyno number—it was creating a calibration that riders could confidently use on tight, technical trails as well as wide-open lake runs.

At 270 horsepower, throttle modulation becomes critical.

That's why the Precision EFI Stage 2 features a carefully developed torque curve that delivers power progressively and predictably, allowing the rider to confidently apply the throttle when exiting corners or accelerating through rough terrain.

The result is a sled that feels incredibly powerful while remaining easy to control.

Supporting Modifications Required

The Stage 2 calibration requires:

• A complete performance exhaust system
• Appropriate clutch calibration

These supporting modifications ensure the engine operates safely while delivering the advertised performance.

Factory ECU Protection

The factory ECU used on this platform is an exceptionally sophisticated engine management system.

One of its greatest strengths is its highly effective knock control strategy, continuously monitoring combustion and adjusting ignition timing whenever necessary to protect the engine from detonation.

Because of this advanced protection system, external knock warning devices are unnecessary. The factory ECU already provides the safeguards needed to maintain engine reliability when properly calibrated.

Every Precision EFI reflash is engineered to work with these factory protection strategies—not against them.

Precision EFI Knock Protection

Every Precision EFI ECU calibration fully retains and optimizes the factory Knock Protection System, providing continuous engine protection while allowing the engine to safely produce maximum performance on 91-octane pump gas.

Perfect for Trail Riding

The Stage 2 was developed for riders who demand exceptional performance without compromising everyday usability.

Whether you're accelerating out of tight corners, making quick trail passes, or covering hundreds of miles in a weekend, the Stage 2 delivers the perfect combination of:

• 270 horsepower on 91-octane pump gas
• Instant throttle response
• Smooth, controllable power delivery
• Outstanding reliability
• Confidence-inspiring trail manners

It's the calibration for riders who want their sled to feel like an entirely different machine—while still having the confidence to ride it all day, every day.
