Description

After much research and development, Unitronic’s comprehensive ECU re-calibration refines and boosts the performance of the A4 B8 2.0L TSI 2008+ and sets the industry standard for reliability and power. The refinements in power delivery provide a large increase in low RPM torque as well as a substantial increase in top end power delivery. Tuning with all factory safety limiters maintained, Unitronic offers performance software and hardware to match your demand for performance and reliability.
