The Audi RS6 C7 Avant is already a legend — a luxury super-wagon capable of outpacing sports cars while offering everyday usability. But for those who demand more than stock, Evo Performance’s Stage 1 ECU and TCU upgrade delivers the raw power, sharper response, and auditory aggression this platform was built to unleash.
Our Stage 1 performance package is engineered specifically for the 4.0 TFSI twin-turbo V8 — enhancing the RS6’s already potent foundation into something truly ferocious.
WHAT’S INCLUDED IN STAGE 1
| Component | Function |
|---|---|
| ECU Remap | Custom tuning of engine parameters for power, torque, throttle response |
| High-Flow Downpipes | Improves exhaust flow, reduces backpressure, enhances turbo efficiency |
| TCU (Transmission) Remap | Reprogramming of shift points, torque limits, and clutch behavior |
ECU REMAP – OPTIMIZED POWER DELIVERY
Our custom Stage 1 ECU software transforms the RS6’s power delivery by refining ignition timing, boost control, fuel delivery, and torque management.
Significant power & torque gains across the rev range
Enhanced turbo response and reduced lag
Peak figures of 500–530 kW and 900–950 Nm torque
Calibrated to run on 95 RON, 98 RON, or ethanol blends (optional)
DOWNPIPE UPGRADE – SOUND & FLOW
To unlock the full benefit of the ECU tune, we recommend installing high-quality stainless steel downpipes:
Reduces exhaust backpressure and increases turbo efficiency
Improves exhaust sound with a deeper, more aggressive tone
Supports cooler EGTs (exhaust gas temps) for long-term reliability
Optional high-flow cats or decat depending on emission requirements
TCU REMAP – TRANSMISSION, UNLEASHED
The stock ZF 8HP automatic gearbox is capable — but restricted by factory torque caps and conservative shift logic. Evo’s TCU remap transforms the RS6’s driving dynamics.
Raises torque limiters to handle increased output
Faster shift speeds under acceleration
Optimized shift points for sportier or smoother transitions (Drive, Sport & Manual modes)
Improved clutch pressure and durability
Enhanced launch control behavior for more consistent take-offs

CONSIDERATIONS
| Item | Recommendation |
|---|---|
| Fuel Quality | 95 RON minimum; 98 RON recommended for peak output |
| DSG Tune | Mandatory to handle torque safely and reliably |
| Exhaust System | Decat or high-flow cat recommended for full-stage benefit |
| Maintenance | Ensure spark plugs, coils, and fluids are up-to-date |
| Emissions Compliance | Decat pipes may not pass roadworthy in certain regions |
UNLEASH YOUR RS6 C7 WITH EVO STAGE 1
Whether you’re looking for a more engaging daily drive or the ability to blow past supercars on the autobahn, the Evo Performance Stage 1 package is your entry into the true capabilities of the RS6 C7. It’s not just a tune — it’s a full recalibration of performance, sound, and character.
📲 Contact us today to schedule your install, view live dyno sessions, or plan your progression to Stage 2 or Stage 3.
For those who have already experienced the thrill of Evo Performance’s Stage 1 upgrade, Stage 2 is the next evolution — a bold leap that integrates advanced cooling, fueling, and airflow enhancements to extract even more horsepower and torque from the mighty RS6.
By combining intelligent tuning with precise hardware upgrades, our Stage 2 package enhances not just performance, but responsiveness, thermal control, and long-term durability, ensuring your RS6 feels as fast and refined as it sounds.
WHAT’S INCLUDED IN EVO STAGE 2
| Component | Function |
|---|---|
| Stage 2 ECU Remap | Further optimized for upgraded hardware, WMI, and higher boost levels |
| Downpipes | Frees up exhaust flow, reduces backpressure, and improves turbo efficiency |
| Cold Air Intakes | Ensures dense airflow, increasing combustion power and throttle response |
| High-Pressure Fuel Pumps (HPFP) | Maintains precise fueling at higher loads and RPMs |
| Water-Meth Injection (WMI) | Cools intake charge, raises octane ceiling, lowers EGTs |
| TCU Remap (Transmission) | Increases torque limits, sharpens gear shifts, improves drivetrain response |
ECU REMAP – STAGE 2 CALIBRATION
Building upon the Stage 1 software, our Stage 2 remap recalibrates engine parameters to fully utilize the improved hardware:
Boost targets raised intelligently to match fueling and cooling limits
Timing advance safely increased with support from WMI and HPFP upgrades
Integrated WMI map scaling for seamless adaptation to meth injection
Tuned for 95/98 RON or WMI-blended octane performance
WATER-METHANOL INJECTION – ADVANCED COOLING
WMI is the key to safely running higher power on pump fuel:
Cools intake temperatures to prevent detonation under boost
Raises effective octane by reducing charge air heat and knock sensitivity
Allows for more aggressive ignition timing and consistent power in hot climates
Reduces exhaust gas temperatures (EGTs), increasing engine reliability
Fully integrated into ECU tuning with failsafes and power compensation
TCU REMAP – GEARBOX REDEFINED
The Stage 2 power increase demands smarter gearbox logic. Evo’s TCU tune includes:
Raised torque limiters to handle up to 1,100+ Nm safely
Faster and smoother upshifts and downshifts
Improved launch control calibration
Dynamic shift strategies for Drive, Sport, and Manual modes
