The Precision EFI Stage 5 is the world's highest-performing kit designed for trail riding. It delivers phenomenal torque and instant throttle response with no turbo lag. Ultra-efficient and so fast that it makes you feel invincible.
Imagine what it feels like to have 350 horsepower running on 91-octane fuel.

Please take note that this power package requires the addition of some adjustable ramps in the primary clutch
Ramp adjustment starting point
For a stock spring and helix combination in good condition, to achieve the target RPM. Please note; a modified spring and helix combination affects the final result. Therefore, we cannot provide settings for every application.
The test should be performed as follows: accelerate quickly but gradually to avoid track slippage. While accelerating, wait for the RPM to stabilize, then take an RPM reading. If the RPM is too high, add weight; if too low, reduce the weight.
Note that surface conditions vary and affect RPM.
- Target RPM: 9100-9300
