034Motorsport is proud to offer our Stage 1 Performance Software for the 2.5 TFSI engine found in the 8J Audi TTRS!

034Motorsport's extensive racing experience with the TT RS led to the development of a new line of performance software for the 2.5 TFSI's Bosch MED 9 ECU, which was initially introduced with the RS500 Tuning Package. 034Motorsport spent a significant amount of time developing and verifying our proprietary software to ensure that our Audi TT RS Performance Software delivers consistent, reliable power under grueling track conditions.

Through optimization of the factory ECU's boost, fueling, and timing maps, the 034Motorsport Stage 1 Audi TT RS ECU Upgrade brings out the potential of the 2.5 TFSI engine.

Peak boost ranges from 20-22 PSI (octane dependent) and tapers to 14.5 PSI by the new 7,100 RPM redline to keep the turbo running at its optimum efficiency. 034Motorsport's Stage 1 boost mapping makes the most from the stock turbo, resulting in increased horsepower and torque throughout the powerband. This software provides rock-solid performance lap after lap, and is combined with an advanced boost control strategy that allows for increased precision beyond factory limits.

Going beyond power improvements, 034Motorsport's calibrator also made improvements to the throttle mapping, increased idle stability, and enabled left-foot braking. The end result is a tune that drives better than the factory calibration, with power delivery that is consistent and manageable on the street and track alike.

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

Please Note: Not for use on emissions-controlled vehicles in California. This software upgrade is for off-road, track, and racing applications only.
