Vehicle-specific tuning figures vary by ECU, software version, gearbox and hardware. RemapIQ verifies the exact vehicle before programming.
The Audi A5 2.0 TDI is a good fit for a conservative Stage 1 calibration because the car already has strong long-distance manners. The benefit is more flexibility in the middle of the rev range and less need to force a downshift for normal road use.

What changes with Stage 1?
Stage 1 improves mid-range torque and throttle response. On the A5 that usually makes the car feel more relaxed and decisive without changing the character of the vehicle.
Expected power and torque
Typical gains vary by factory output, but the car usually lands in the 190–240 bhp range with a noticeable torque increase.
What we check first
We check the same fundamentals as other modern diesels: DPF, EGR, boost control and battery health.
Known vehicle-specific considerations
- The A5 is often a long-distance car, so smooth delivery matters more than an aggressive map.
- If the car has a multitronic or DSG-style gearbox, support depends on the exact transmission.
- We keep the calibration conservative if the vehicle is used for towing or heavy motorway mileage.
