Audi A4 Avant B8.5 2.0 TDI S-tronic – Stage 1 (177 → 210 HP | 380 → 430 Nm)

A clean and safe calibration for drivers who want stronger acceleration and smoother daily performance.

The facelifted Audi A4 B8.5 equipped with the 2.0 TDI EA189 engine and 7-speed S-tronic gearbox responds extremely well to a carefully developed Stage 1.Our calibration raises power from 177 to 210 HP and torque from 380 to 430 Nm, transforming the car’s mid-range performance.

What we improved

• Boost and torque limiters

• Injection maps for clean AFR

• Rail pressure optimization

• Smoother torque delivery across the rev range

• Faster throttle response

• DSG behavior under load (keeps ideal rpm for acceleration)

Safety & reliability

• Turbo pressure within factory limits

• DPF operation fully preserved

• EGT under control thanks to clean combustion

• Zero smoke even at full load

• Verified with real driving logs

Driving impressions

After tuning, the A4 accelerates earlier, harder and more confidently.The 7-speed DSG gearbox benefits strongly from the added torque — overtakes are shorter, highway pulls are smoother, and daily driving feels more effortless.
