Revo Software offers a perfect balance of performance, economy, longevity and safety. Development and testing of Revo performance software is done in a number of territories around the world, taking into account variations in atmospheric conditions such as altitude and temperature.

Power increases depend very much on the hardware, settings and fuel being used. The up-rated fuel system allows much more power throughout the rev range but specifically in the midrange where the stock setup is insufficient. Stage 4 software is boost, fuelling and timing adjustable allowing the vehicle to be setup to suit the fuel quality, driving conditions and driver preferences.

Testing facilities at their UK Headquarters and US Development Facility, as well as a track office at Bruntingthorpe Proving Ground, Revo are able to test their products extensively on and off track. Testing products in this way is paramount to ensuring that along with more useable power and torque comes refined drive-ability, something often overlooked.


Testing on a dyno will only ever tell part of the story. Revo believe in data-logging on the road and racetrack as well as testing in controlled dyno conditions, to give you a clearer picture of the performance you can expect. This plays an important role in the Revo development process, ensuring the highest quality products that perform where and when it matters most.


Access to vehicles is imperative to development and testing. Revo run one of the most extensive fleets in the industry, and have access to hundreds of other beta vehicles via a global Authorised Dealer Network. These vehicles not only demonstrates what is capable using Revo products, which cover thousands of miles in a multitude of climates, but also ensures that vehicles perform in any scenario, from a trip to the local shops to an epic adventure in the Alps.
