Stage 1 software details for your AUDI, RS4, 4.2 RS4 Naturally Aspirated (414 bhp)
Stage1 software, developed over months of rigorous testing, has been designed to maximise the potential of the standard 4.2 engine; giving more low end and midrange torque and much better power throughout the rev range along with removing the speed limiter and raising the rev limit to 8400rpm. Being adjustable the software can be setup to suit conditions and fuel quality. Throttle response is a personal preference; lower settings give you more control using the throttle and higher values can give the car a very aggressive ‘feel’ when you lightly touch the throttle, neither is wrong so the setting is setup to suit the individual driver and the conditions the car is being used in. Fuelling and Timing adjustment is setup to suit the fuel quality run and again conditions. If the car is being used in a various conditions the Revo SPS is very beneficial, the three user pre-sets can be setup to give a number of performance setting combinations.
