Stage 4+ Performance Software has been specifically developed to attain the best possible performance from the RS with the bolt-on performance modifications from Stage 4 however, is specific to cars with up-rated fuel pumps and inlet manifolds. Please click on the hardware tab for specific requirements. The up-rated fuel system allows much more power throughout the rev range but specifically in the midrange where the stock setup becomes insufficient at this performance level. Stage 4+ software is boost, fuelling and timing adjustable allowing the vehicle to be set up to suit the fuel quality, driving conditions and driver preferences. We've specifically calibrated the software to improve the performance of the entire rev range and can be tailored to your specific requirements with our unique software adjustability.

Get far more than a peak power figure.

Revo offers some of the most substantial performance increases on the market, however, only the driven know that peak figures form part of a much bigger picture and are never the sole focus during Revo’s development process; it’s all about the drive. Only Revo offers a perfect balance of performance, economy and engine longevity.

Revo performance ECU Software gives you much more than just an increase in power and torque. A large part of development is based on driving scenarios and feedback; our calibration doesn’t just offer great dyno curves and peak power/torque figures but an exhilarating driving experience. Expect smooth and refined response at low RPM & partial throttle, with huge gains at wide-open throttle and throughout the whole rev range.

Switchable and fully adjustable software 1



Only Revo operates a Global Development Programme through its network of over 400 Revo Authorised Dealers worldwide. Access to vehicles on this scale enables the calibration team to fine-tune products before release, testing products in a wide range of climates and conditions including altitude, fuel quality, humidity. This also allows Revo to test how Revo products perform in different driving scenarios and formed a vital part in the development of Performance ECU Software.

Developed on the racetrack, ready for the road.

The Revo tuning philosophy ensures that impressive performance benefits are balanced with useable, reliable power delivery that enhances the way you can drive your vehicle. Development on the road and racetrack as well as testing in controlled dyno conditions gives you a clearer picture of the performance you can expect from Revo ECU Software. Testing in this way plays an important role in ensuring the highest quality products and delivering the driving experience expected.

Only Revo performance ECU Software maintains and enhances factory safety levels along with additional driving features. With the SPS Software Switch, you can even customise three performance modes depending on the fuel you use and your running conditions.




Using an SPS switch you can take advantage of the switch-ability of Revo software. The Patented OBD2 interface is the ultimate compliment to Revo performance software, giving you the ability to switch between stock and 3 adjustable performance modes via the vehicle OBD port.

Performance Modes can be customised to our preferences e.g: Low octane specific, high octane specific, low boost/high boost, or valet mode. Speak to your Revo Authorised Dealer

  • SPS Position 1 – Stock Mode
  • SPS Position 2 – Performance Mode A
  • SPS Position 3 – Performance Mode B
  • SPS Position 4 – Performance Mode C
  • SPS Position 5 – Anti Theft Mode ON
  • SPS Position 6 – Anti Theft Mode OFF

Simply select a program, plug in, wait a few seconds, remove the SPS device and start the car. It's simple and there's no fixed switch to install in the vehicle. With the MED9 ECU and Revo adjustable Software, settings will default to the equivalent of stock when the battery is disconnected. The SPS or your Revo Authorised Dealer can be used to reset the performance mode settings. Learn More.
