Each of our tunes only optimizes the performance of your engine without impacting reliability. During development, the tunes are pushed to the point at which the motor would begin to "knock" and potential failure could occur. From there the adjusted parameters are significantly backed down to a safe level where they are then reliability tested for over 200 hours both on an engine dynamometer and in the water before they are released to the public.

No. It actually increases your fuel mileage. By increasing the power of the motor, it becomes more efficient by lowering the RPM needed for operating at the same speed. On average our customers see a 15% increase in fuel economy; though some of our customers have seen far more, especially on boats with multiple engines.

Up to 130hp depending on the output of your motor. Individual product pages have dyno graphs showing powerband improvements.

To minimize the cost of production, manufacturers like Yamaha produce one outboard engine platform that can support multiple levels of power. Example: The Offshore V6 F225 is mechanically identical to the Offshore V6 F300. The only difference between the two is the calibration. We are effectively applying the power that the factory has removed for detuned models plus a bit of increased performance in certain areas of the tune.

Most of our clients do not need to change props after tuning to experience the benefits. However, you can change props at any time to suit your goals, whether that be more top speed, better hole-shot, or fuel milage.

No. We proudly offer remote tuning solutions for most of the western hemisphere at the same cost as our local, white-glove service. Upgrade turnaround in as few as three days.

Absolutely. All of our tunes yield better fuel economy than a stock Yamaha. Many of our tunes produce an average of 10-15% increase in fuel economy which means less fuel/saving money and increased range! Email us for more details on your specific engine and set up.

If you are local to us in VA or New Jersey, you can come to us for NizPro tuning while you wait OR arrange for us to travel to your boat for tuning. Email or call us for more information, pricing and scheduling.

NizPro tuning involves small adjustments to your ECUs parameters to optimize the combustion process. It is 100% reversible at any time (we always include flashing back to stock for any reason at no cost - you just pay shipping). The NizPro tune safely and reliably increases power output, improves fuel economy, and reduces emisions. NizPro is the world leading tuner of Yamaha outboards. Our "competition" cannot match the combination of power increase, fuel savings and emissions reductions that each and every Nizpro tune delivers.

We are your local NizPro dealer for the Commonwealth of Virginia and New Jersey. Our main location is conveniently located in Richmond, VA and our satellite location in Cape May County, NJ. In many cases we can arrange for onsite tuning throughout VA and NJ and often states in between (MD and DE). Reach out to us to discuss!
