Stage 2 software details for your AUDI, S5, 4.2 Naturally Aspirated (350 bhp)

Stage 2 Performance Software has been specifically developed on our own test vehicles to attain the best possible performance from the 4.2 with a bolt on performance exhaust giving even 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. Stage 2 allows you to run a sports cat or de-cat without the CEL (Check Engine Light) being triggered by a ‘CAT Efficiency’ error code. Stage 2 software is Throttle, Fuelling and Timing adjustable with slightly more flexibility than Stage 1 allowing the vehicle to be setup to suit the fuel quality, driving conditions and driver preferences. Stage2 typically gives great gains throughout the midrange.
