Performance Software

All Revo performance Software is designed to safely enhance the driveability of your vehicle, giving access to more power and torque throughout the rev-range while maintaining the extensive factory safety mechanisms. Although Revo offer some of the most substantial performance increases on the market, peak figures form part of a much bigger picture and are never the sole focus during development. 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. The Revo R&D process is the most extensive and in-depth in the industry, giving you a product you can trust and an experience you wont forget.

Stage 4 Performance Software has been specifically developed to attain the best possible performance from the RS with the bolt on performance modifications as per Stage 2, however is specific to cars with up-rated fuel systems. 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. Stage4 software is designed for customers who already have the following hardware installed. If building a car Revo recommend following the Stage4+ specification.

Research and Development

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.

On-Road Testing

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.

Development Vehicles

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.
