C5 Audi RS6 4.2T Performance ECU Software

034Motorsport is proud to offer our C5 Audi RS6 Stage Tuning Software for the 4.2L Biturbo V8 Engine found in the 2003-2004 Audi RS6 Quattro!

Through optimization of the factory ECU's boost, fueling, and timing maps, the 034Motorsport 4.2T Stage 1 Tune is able to safely provide increased horsepower and torque, as well as a much broader powerband. 034Motorsport's engineers have also addressed other shortcomings of the factory calibrations by increasing the rev limit to 6,800 RPM, and refining part-throttle mapping for improved drivability.

With the 034Motorsport C5 Audi RS6 Stage 1 Tune, you can expect faster acceleration, increased peak horsepower, huge increases in low-end and midrange torque, improved throttle response, and a much broader powerband!

This tune was developed in-house by 034Motorsport's expert calibrator, and was thoroughly tested on the street, track, and dyno before release.
