Stage 2 software details for your AUDI, S4, 4.2 Naturally Aspirated (340 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. 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.
