Engine Platform Review
Measured EA825 4.0T examples across Audi RS, Lamborghini Urus, and Porsche Cayenne applications.
These are separate vehicles sharing the same engine family. Hardware, software, fuel, condition, and supporting modifications still determine the correct path for each car.
What Our Data Shows
The published EA825 4.0T Twin-Turbo examples finish between 604 and 634 WHP, with measured gains ranging from +84 to +197 WHP. That spread is useful because it shows why the correct plan must start with the actual vehicle.
What It Does Not Promise
Fuel, hardware, software, transmission, condition, access requirements, and the owner's goal all change the scope. Vollux uses these results as proof of process—not as a guaranteed number for every EA825 4.0T Twin-Turbo vehicle.
How We Build the Quote
Send the year, model, VIN, transmission, current software, complete modification list, fuel, warning lights, and goal. We will confirm the supported tuning, access, TCU, dyno, or diagnostic path before scheduling.

EA825 4.0-liter twin-turbo V8 examples. Older C7 RS6/RS7 and earlier Cayenne GTS models are not assumed to use this engine.
Final compatibility, unlock requirements and transmission tuning availability are confirmed by VIN, engine, ECU and current software before quoting. Check my vehicle and get a quote.
Clear Starting Prices
ECU pricing applies to supported applications. Dyno testing, access or unlock requirements and any additional scope are confirmed in your written quote.
Calibration First
Best for: Healthy stock or lightly modified supported vehicles
A platform-specific calibration plan built around the actual vehicle, fuel, modifications, and intended use.
Measured Validation
Best for: Owners who want the calibration tested and measured under load
Add in-house AWD Dynojet testing to your tuning plan. Dyno time is quoted separately for the vehicle and scope.
Complete Drivetrain
Flat price $400
Best for: Supported vehicles needing shift and torque strategy matched to engine output
Review transmission software support, current behavior, torque management, and the value of coordinating ECU and TCU work.

Platform Tuning Questions
No. Starting prices show the base service scope. Controller access or unlock, licensing, interfaces, additional fuel files, hardware, diagnosis, installation, and unsupported software paths may change the total. Vollux confirms the complete written price for the exact vehicle first.
No published result is a promise. The examples differ in hardware, fuel, software, condition, transmission, and goals. We will explain which comparison is relevant and what cannot be assumed.
Not every supported vehicle needs the same process. Dyno validation is the clearest option when you want measured output, a before-and-after comparison, or controlled testing of a modified setup under load.
Send the year, model, VIN, transmission, current software or tuning platform, complete modifications, fuel, warning lights or drivability concerns, and the result you want from the car.
