Custom Tuning starts at $1699. 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.

Increase rear wheel torque transfer and traction with our Haldex Tune for the Gen 5 OCQ. During testing, our development vehicle improved 60 foot times to 1.53sec (on street tires) when paired with our optional Haldex Spring Upgrade (and Stage 3 ECU and TCU tunes). When tested on drag radials, the 60 foot time further improved to 1.50sec.
Increases pump duty cycle for increased torque transfer to rear wheels, typically from 20% - 25%
Increases torque transfer during cornering to promote oversteer
Retains factory decoupling when cruising to maintain fuel economy
Reduced 60ft times for those who like to race
Pairs perfectly with our Haldex Spring Upgrade (not required and sold separately)
To flash your Haldex module, you will need a FlashZilla Pro dongle.
Applicable to:
2015 - 2019 VW Golf VII R
2017 - 2022 VW Golf Alltrack / Sportwagen
2015 - 2020 Audi A3 / S3
2016 - 2022 Audi TT / TTS
2018 - 2022 Tiguan 4motion
*some 2019-2020 S3, TT/TTs are not compatible with our tune
With this software, you can optimize the performance of the Haldex system in your car. The software can set the oil pump to its maximum DC capacity during heavy load conditions.
The software smoothly controls the oil pump and adjusts its operating force, which in turn affects the force of the Haldex clutch, based on the vehicle's current situation (calm driving, dynamic driving, or launch control).
This ensures your system won't be overloaded when there's no need for high settings.
It is ideal for all users and for every situation the vehicle might encounter. The software can function like the stock file of your factory controller but can also boost its operating power by up to +/-40%.
After a Haldex reflash, it's essential to recalibrate the oil pump, using tools like VCDS or OBD11.
At TuneZilla, we strive for an OEM level of drivability and reliability. Our team of Calibrators from around the world painstakingly work to deliver repeatable performance on all of our base maps. One of the major differences between our tunes and most of our competitors tunes is our linear OEM like throttle response. Where some software tuners increase throttle response to mask the actual output of their tunes by giving a very peaky feeling under acceleration, our tunes are designed to make the most usable and consistent power curve possible to maintain a strong pull without a heavy fall off midway through the power band. All while generating peak power as early as possible in the RPM range. Most off the shelf tunes advertise an attractive peak power figure, but suffer from a sudden drop in torque and a lower torque curve throughout the remainder of the RPM range.

The Stage 2 files for the 1.8T EA888.3 engine satisfies the gap that separates the Golf 1.8T from the GTI 2.0T. Increasing output to an eye watering 250 ft-lb of real, usable torque, our Stage 2 files also improve throttle response and drivability to a level that feels akin to the flagship FWD hot hatch of the VW brand, leaving your wallet with more room to breath so you can upgrade tires and brakes to hunt down GTI's on the open track.

Flex Fuel is now supported on our Stage 3 tunes for the IS20, IS38 and 2260S. With this innovative feature, you can harness the incredible potential of ethanol to boost your vehicle's horsepower and torque, all while enjoying the benefits of a cleaner, more efficient engine.
How it Works: Our flex fuel tune is designed to allow you to seamlessly blend ethanol into your fuel, optimizing your engine's performance. As you gradually increase the ethanol content in your fuel mixture, you'll experience a noticeable boost in power. The magic begins at E10 and increases incrementally up to E65, giving you full control over your vehicle's newfound capabilities.
Simple upgrade for Major gains: Simply add an ethanol sensor to your vehicle, and your TuneZilla software will do the rest. Our tune files will automatically detect when there is an ethanol sensor installed and start adapting your tune to the ethanol content you've put in the tank. Multi-Port Injection is also required for this feature. Please check our MPI requirements in the Technical Guide to make sure your MPI setup will work with our Stage 3 files.
Safety First: Rest assured, we've designed our Flex Fuel feature with your safety in mind. It includes built-in safeguards to prevent excessive ethanol blending and protect your engine from potential harm. We prioritize your well-being and the longevity of your vehicle.
