Three Factory Riding Modes—Completely Reimagined

The factory handlebar controls continue to give you instant access to three distinct riding modes, each carefully calibrated for a different riding experience.

ECO

Designed for maximum fuel efficiency and long-distance touring without sacrificing smoothness.

STANDARD

A substantial improvement over the factory calibration, offering stronger acceleration and excellent drivability for everyday trail riding.

SPORT

The full 180 HP experience. Immediate throttle response, explosive acceleration, and a riding experience that completely transforms the sled.

It delivers the crisp, instant response and excitement of a high-performance two-stroke—with the smooth torque and reliability of the 900 ACE Turbo.

No Hardware. No Guesswork. Just More Performance.

Unlike many performance packages, Stage 1 requires no clutch modifications, no exhaust, no intake, and no additional components.

Simply reflash your factory ECU and enjoy a completely different machine.

Because the calibration was designed around the stock clutching, it performs exceptionally well with the OEM clutch and ramps, making installation simple while preserving factory drivability.

Engineered for Reliability

Precision EFI believes the best performance upgrade is one you can trust season after season.

Our Stage 1 calibration is carefully developed to work within the capabilities of the factory engine and turbo system while preserving the OEM safety strategies built into the ECU.

The result is a snowmobile that feels dramatically more responsive, accelerates harder, and remains as enjoyable to ride on the last mile of the season as it was on the first.

The Perfect First Upgrade

If you're looking for the biggest performance gain with the simplest installation, Precision EFI Stage 1 is the answer.

No additional parts. No complicated setup. Just 30 extra horsepower, nearly double the throttle response, improved fuel economy, and the confidence of a calibration engineered for long-term reliability.
