Our Stage 1 tune for the 2.0L EA288 (CRUA/CVCA) TDI delivers a substantial increase in horsepower and torque while maintaining the refined drivability expected from a modern diesel. Revised engine management provides stronger low-end torque, improved mid-range pulling power, and more responsive acceleration throughout the RPM range. The result is a more capable and engaging vehicle that retains the everyday practicality of the EA288 platform.
No hardware upgrades are required to run Stage 1, making it an excellent upgrade for completely stock vehicles. The factory DSG transmission can comfortably accommodate the increased engine output without requiring a TCU tune. For those looking to further refine their driving experience, our optional DSG tune introduces revised transmission behavior, including adjusted shift points and refinements to the Drive and Sport modes. These changes allow the transmission to make better use of the additional torque while providing more responsive and consistent shifts.
Installation is completed conveniently at home using our FlashZilla Pro device and the TuneZilla Portal app. Simply connect to the vehicle through the OBD2 port, download your tune, and flash directly to the ECU without needing to schedule an appointment or visit a dealer. Our flashing process also allows you to read and save your original factory file, giving you the flexibility to return to stock when needed.
With its combination of increased power, refined drivability, and straightforward installation, our Stage 1 tune is an excellent starting point for EA288 TDI owners looking to get more out of their factory hardware.
Our Stage 2 tune takes the EA288 further, delivering an even more aggressive engine management setup designed to extract additional output from the factory powertrain. With increased horsepower and torque, the engine takes on a stronger character, offering a more forceful delivery and improved pulling power across the RPM range. The revised power delivery makes a noticeable difference under acceleration, giving the EA288 a much more capable feel while retaining the smooth, predictable characteristics that make it enjoyable as an everyday vehicle.
One of the biggest advantages of our Stage 2 tune is that it does not require any additional hardware modifications. This is the highest available ECU tuning stage for the EA288 that can be run on completely stock engine hardware, making it an excellent choice for owners who want to take their vehicle further without committing to a new turbo, or other supporting upgrades. The factory DSG transmission can continue to be used without any additional tuning. A DSG (TCU) tune is not required to support Stage 2, allowing you to enjoy the increased engine output while retaining your existing transmission software. Customers who wish to explore additional transmission features can consider an optional DSG tune, but it is entirely optional.
For EA288 TDI owners looking for the most our tuning has to offer while keeping the factory turbocharger and supporting engine hardware, Stage 2 delivers an excellent balance of substantial added power, everyday usability, and flexibility without requiring a hardware upgrade.
Our Stage 3 tune takes the EA288 beyond the capabilities of its factory turbocharger, introducing a higher level of output through the use of an upgraded turbo. With the additional airflow available from a larger turbocharger, our Stage 3 engine management is designed to take advantage of the increased capacity and deliver a substantial step forward in horsepower and torque. The result is a stronger powerband, and sustained acceleration that gives the EA288 an entirely different character.
Unlike Stage 1 and Stage 2, Stage 3 requires an upgraded turbocharger to support its increased airflow requirements. The factory turbocharger is no longer sufficient for this level of tuning, making a suitable turbo upgrade an essential part of the build. Actual performance will depend on several factors, including the vehicle's EGT limiter and the potential for boost creep.
The factory DSG transmission can still be used without additional tuning, as a DSG (TCU) tune is recommended, but not required for the Stage 3 ECU tune. However, customers looking to complement the increased engine output can opt for our DSG tune, which raises the transmission torque limit and introduces revised shift behavior for smoother, more consistent gear changes.
For owners seeking a power increase beyond what the factory turbocharger can offer, this tune is a great choice.

Custom Tuning starts at $1999. To get a more accurate cost on your custom tune, please create a ticket and tell us more about your build, and your specific modifications.
If you feel that our existing tune offerings will not work for your application or your intended use, you can request Custom Tuning. Custom Tuning must be requested through our Tickets, and you must provide vehicle information as well as hardware (upgrades) information. Once submitted, our team of calibrators will evaluate your request and determine if Custom Tuning can achieve your goals and if they are able, your Tune Request will be accepted.
Custom Tuning requires heavy participation from the Customer, either through an Authorized TZ Dealer or the Customer themselves. TuneZilla Calibrators will require that the vehicle has access to dyno time when needed, and data logging is required. If you are not comfortable with data logging, and if you may not be able to access a facility with a dyno (many facilities will rent dyno time) custom tuning may not be possible for you.
Custom Tuning vs. Off The Shelf Tuning
We understand that our end users have varying driving styles and build purposes, which is why we offer revisions on all of our Off-The-Shelf tunes. By offering Custom Tuning to our customers, we can be sure you are getting the most out of your vehicle with your specific parts upgrades. Our OTS (off-the-shelf) maps are tested in house with as many variables as possible to ensure even if you don’t want to customize your tune, your vehicle’s OEM sensors and adaptations will still be able to optimize our tunes to your region’s fuel and most bolt-on upgrades. Tune Revisions are not the same as Custom Tunes. See our Terms and Conditions for our re-tune policy (section 4b)
We believe it’s important for our customers to understand what is happening inside their engine so they can make informative decisions. Our LOG VIEWER automatically generates your vehicles data log .csv files into easy to read graphs which can then be viewed by our Calibrators to find areas of optimization on your vehicle. Not only can this data be used to optimize your tunes, but a lot of troubleshooting and diagnosing can be done by comparing requested data to actual data at a glance.
In many cases, custom tuning is not required. If you are unsure if you will benefit from a Custom Tune, you can reach out to our team and upload data logs for them to examine.
