Audi A6 3.0 TDI Stage 1 Remap

Our Stage 1 ECU remap is designed to optimise the factory engine management software without requiring additional performance hardware modifications.

The standard Audi A6 3.0 TDI produces 245 BHP and 580 Nm. Following a Stage 1 remap, estimated performance can increase to approximately 300 BHP and 650 Nm of torque, delivering stronger acceleration and improved in-gear performance.

Benefits of a Stage 1 remap include:

• Increased horsepower
• Increased torque
• Improved throttle response
• Stronger acceleration
• Improved in-gear performance
• Smoother power delivery

Our calibration is developed around the vehicle’s engine and ECU configuration, with the aim of delivering responsive performance while maintaining suitable operating parameters.

Audi A6 3.0 TDI Stage 2 Tuning

For owners looking for further performance, Stage 2 tuning can offer additional power when combined with suitable supporting modifications.

With the appropriate hardware and calibration, the Audi A6 3.0 TDI C7 may achieve up to approximately 320 BHP and 680 Nm of torque.

Stage 2 tuning may require supporting upgrades depending on the vehicle’s configuration, condition and intended use. These can include suitable intake, intercooling and exhaust upgrades where compatible.

Exact gearbox and control unit compatibility must be confirmed before any gearbox software work is undertaken.

Before Tuning

Before carrying out any remapping work, we recommend checking the overall condition of your Audi A6 3.0 TDI. A vehicle should be mechanically healthy before its engine software is modified.

Our pre-tuning checks may include:

• Engine fault-code diagnostics and a review of stored faults.
• Fuel system and injector condition checks.
• Turbocharger operation and boost pressure checks.
• Intake system inspection for leaks or restrictions.
• Fuel delivery and fuel pressure checks.
• Cooling system condition and operating temperatures.
• DPF and emissions system checks.
• General engine condition and any signs of mechanical concerns.
• Drivetrain and transmission condition checks.
• ECU identification and software compatibility checks.

These checks help identify potential issues before tuning and allow us to establish whether the vehicle is suitable for the requested calibration.
