034Motorsport's Stage 1 Performance Software is now available for the high output 1.8T engine found in the 8N Audi TT225!

034Motorsport’s years of racing and tuning experience with various 1.8T-powered platforms led to the development of a new line of performance software for the Audi TT225 1.8T's Bosch ME7 ECU. 034Motorsport's calibrator spent a significant amount of time developing and verifying our proprietary software to ensure that our TT225 Performance Software delivers consistent, reliable power on the street, as well under grueling track conditions.

Through optimization of the factory ECU's boost, fueling, and timing maps, the 034Motorsport Stage 1 Audi TT225 Tune provides substantial increases in horsepower and torque throughout the powerband.

Going beyond power improvements, 034Motorsport’s calibrator also made improvements to the throttle mapping, increased idle stability, and removed the speed limiter. 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.
