I'm looking at this performance chip (info below) for my Utopia 205 boat, wondering if anyone has tried it. It costs $65. thoughts/comments welcome, thanks.

Dyno-BOOST is a fully adjustable performance fuel controller designed for fuel injected PWC's. It tricks signals being read by the ECU, resulting an adjustment to the fuel curve, which is what causes the increase in HP, as well as improves acceleration and throttle response within the entire RPM range, simply wires inline with factory IAT (Intake Air Temperature) or MAF (Mass Air Flow) sensor and plugs into the O2 sensor harness on models having it. Crisp acceleration, much more horsepower and torque, lower quarter mile times and fine throttle response. Installation is easy, no special tools or expertise required. Gain +15-35 additional HP, and extremely dynamic acceleration by up to 30 %. This mod will not affect engine reliability or endurance. Dyno-BOOST tricks the ECU thinking the intake air much more cooler, then the ECU will send more fuel for a richer mix besides if the current vehicle has oxygen sensor it blocks restrictions generated by the ECU.
These vehicle specific chips are sorted into several categories according to relevant sensors' operating ranges. If you don't find your fuel injected application please contact us.
Dyno-Boost is not available to carb models.
FEATURES OF MAGNUM Dyno-BOOST PERFORMANCE CONTROL CHIP MODULE:
* Improves engine output by up to 15 % per adjustment.
* Enhances Nm, throttle response, acceleration and torque in the full RPM range.
* Performance level setting from 0 - 100 %.
* You can set the preferred higher air/fuel ratio than the stoichiometric fuel mix.
* Unit can be switched, breaking +12 V feeding voltage. (switch not included)
* INTEGRATED O2 - OXYGEN SENSOR SIGNAL CONTROL to avoid undesired restriction of ECU (by models fitted with oxygen sensor only)
* Peak up acceleration and dynamism by up to 30 %.
* Results higher top end speed.
* Long duration - 10-year warranty.
* Easy universal 20-minute installation.
* Immediate effect, switchable on the ride
* Reduces flat spots and diminish delay time when rev up.
* It does not affect engine endurance or reliability.
* Bright red light design
WORKING THEORY
Dyno-BOOST will supply modified signals to your Jet's ECU. The ECU then adjusts air/fuel ratio and secondarily timing advance curves to new performance settings, in addition this MAGNUM upgrade does have an absolutely outstanding O2 sensor control circuit integrated into the unit for those editions having oxygen sensor.
This control panel helps to block undesired restriction generated by the ECU.
It tricks the ECU thinking the intake air much more cooler, then the ECU will send more fuel for a richer mix besides if the current vehicle has oxygen sensor it tricks its signal to avoid ECU safe mode and low performance.
Why should ECU limit the mixture's air fuel ratio?
The answer is simple, ECU is calculating the air/fuel ratio also per all sensors' signal, and the last and most important respected control step is the oxygen content in the exhaust gas. If O2 sensor delivers fuel rich signal to the ECU, HP-gain will be limited.
Our evaluation does not let the Oxygen Sensor delivering fuel rich signal accordingly ECU will allow the advanced injection.
There is no risk of any damage to the engine or electrical parts since the modified sensor signal will always remain within the manufacturer's recommended specifications. The unit works in conjunction with your Jet Ski's ECU and will not affect engine reliability at all. This worldwide unique Performance Chip Module can even quickly be switched, removed or re-installed at any time.
