With the Nizpro performance tune, factory 90-horsepower Yamaha SHO engines can increase to 123hp, and factory 115-horsepower Yamaha SHO engines are transformed to 152hp screamers. You will experience a substantial increase in low-end and mid-range torque torque to get you up on plane quicker, and depending on your setup, an increase of 2-5mph in top speed.
NOTE: To achieve optimal performance, your engine must run on minimum 89-90 USA grade / 95-98 AUS grade octane fuel and adhere to recommended service intervals. Failure to do so may result in decreased performance and could potentially damage your engine.

Tuner’s Note:
No brainer: Torque, speed, fuel economy, and range, you're going to get it it all if you have one of these motors.
