Is a remap worth it on the Audi A4 B9 2015?
A worthwhile remap. The gain is clearly felt on the road, especially in the mid-range where the torque increase lands.
What each stage needs
| Stage | Power | Torque | Hardware |
|---|---|---|---|
| Standard | 187 bhp | 400 Nm | None |
| Stage 1 | 232 bhp | 526 Nm | Software only |
| Stage 2 | 232 bhp | 526 Nm | Uprated intercooler, high-flow intake, sports catalyst |
Risk on this engine: medium
- Significant 24% gain: boost and fuelling pushed beyond factory settings.
- Torque rises by 126 Nm (32%): elevated drivetrain and clutch stress.
- Diesel: no knock risk. Primary risks are EGT, turbo health, and injector wear.
How to keep the risk down
- Check intercooler efficiency before tuning.
- Inspect clutch condition before tuning. Check dual-mass flywheel.
- Monitor EGT under hard driving: sustained temps above 700 C accelerate turbo wear.
- DPF (if fitted) will accumulate soot faster: ensure it is in good condition.
- Keep a copy of the original ECU file before flashing.
