Chip tuning Audi A6 C7 3.0 TDI – +50 HP & +90 Nm EDC17CP54
Audi A6 C7 3.0 TDI +50hp +90Nm ECU EDC17CP54
The Audi A6 C7 3.0 TDI is one of the most successful V6 diesel engines in the VAG Group. The customer came in with the goal of improving engine agility and throttle response. We safely modified the EDC17CP54 ECU – the result? +50 HP and +90 Nm of torque while maintaining complete engine reliability.
Customer's car - initial state
-
Model: Audi A6 C7
-
Engine: 3.0 TDI V6
-
Controller: Bosch EDC17CP54, 4G2907401, 10SW028687, 0007
-
Drive: quattro / Tiptronic automatic

Stock power: 272 HP / 570 Nm
-
Customer Goal: Greater flexibility at low revs and faster throttle response.
The car was in very good condition, no errors in the ECU, turbocharger and injectors fully functional.
Modification process – reading, analysis, optimization
Before starting the tuning, we performed a full OBD diagnostics and dynamic logs to verify the engine condition.
The EDC17CP54 controller was read in OBD mode and then analyzed for torque maps, fuel delivery, boost pressure and torque limiters.
We have prepared a proprietary Stage 1 file for this unit, optimized for the safe operating limits of the turbocharger and DPF system.
👉 Stage 1 version – without DPF/EGR off, full compliance with OEM specifications.
The end result – increased power and torque
| Parameter | In series | After modification | Increase |
|---|---|---|---|
| Power (hp) | 269 hp | 319 hp | +50 hp |
| Torque (Nm) | 579 Nm | 670 Nm | +90 Nm |
After the modification, the Audi A6 C7 has gained a completely new character - the engine responds immediately to the gas pedal, and acceleration from 0 to 100 km/h has improved.
Thanks to the appropriate tuning of the torque and boost maps, an increase in power was achieved throughout the entire rev range, without smoking or overloading the accessories.

FAQ – frequently asked questions
Is chiptuning the Audi A6 3.0 TDI safe?
Yes, provided it's performed by an experienced workshop and the modification is based on real dyno data. Our files don't exceed the safe limits of the turbocharger or Siptronic gearbox.
Does tuning affect fuel consumption?
With no changes in city driving, with calm extra-urban driving a fuel consumption reduction of ~0.5–0.8 l/100 km is possible thanks to higher torque at lower revs.
Is it necessary to report chip tuning in the registration certificate?
No, as long as the power does not exceed the factory homologation limits of the model.
