WARRANTY:
Advertised gains are estimates of HP and Torque are gains in ideal conditions and typically show the largest possible change. Actual gains are dependent on the fuel quality, supporting modifications, altitude, ambient temperature, engine condition and other factors.
Fuel quality is very important!. Low quality, old, and/or low octane fuel will greatly impact engine output and potentially even engine health. Top tier brand premium fuels should always be used to achieve the best results possible.
Temperature, humidity, altitude, and air density all impact engine performance. Heat, high humidity, and thin air will all work towards reducing engine output
Higher KM engines generally have lower compression, increased carbon deposits, and timing chain / cam wear. These factors can and will impact engine output. Properly maintained engines will have better performance than abused or neglected engines.
Supporting modifications – The highest power levels require supporting modifications. Depending on the engine, this could mean forged internals, built transmissions, upgraded fuel systems, E85 mixes, port injection etc.
