034Motorsport is proud to offer our C5 Audi RS6 Stage 1 Performance 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.

I had mine reflashed late last year and have been running this to-date without the Tip flash so far. I wasn't expecting massive difference given it's only a software flash, but I was quite surprised at the performance difference! Anyone driving a C5 RS6 is already used to being nudged in the back when the right foot goes down, but this is somewhere else entirely. Power feels a whole lot more urgent, with plenty of low-end pull and no discernible spiking. Yeah, I like it!
