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.

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.

Requirement
Minimum 91 Oct / 95 RON
Required
Clutch Upgrade (manual)
Recommended
DSG Tune
DSG tune is recommended to optimize shift patterns and increase driver enjoyment in Sport and Drive modes
Low Torque files are available for manual transmission vehicles, but an upgraded clutch is recommended
*Map Switching tunes are available as a tune request only. They are not available through the Instatune server.
Selectable in Instatune
Feature
Left Foot Brake Enable
Allows brake pedal and accelerator pedal to be pressed without cutting throttle/fuel.
Works with Stage 1 and up
Overrun Crackle
Extends fuelling request after throttle lift off to create "crackles" or "pops and bangs"
Works with Stage 2 and up
Hard Cut Limiter
Cuts fuel at a set RPM instead of the factory "soft" limiter which limits engine speed/revs at a set RPM
Recommended for track/race use only
when equipped with DSG the limiter will only work in manual mode if auto upshift is disabled
Increased Rev Limiter
Adjust timing to optimize high octane fuel
Adjust boost request values
Increase throttle response for improved pedal feel
Optimized fuel trim adjustments
High and Low Torque files
High oil pressure switch point is lowered for engine longevity
Optional Map Switching*
Optional Left Foot Braking enabled
Optional Overrun Crackles
Optional Hard Cut Limiter
Minimum 93 Oct / 98 RON fuel
Water Meth Injection
Highly Recommended
Clutch upgrade is highly recommended for Stage 2 tunes due to the increased Torque
DSG tune is highly recommended for Stage 2 tunes to maintain drivability with increased torque
*Map switching tunes are available through the Tune Request function on FZL app. They are not available through the Instatune server
Overrun Crackles
MPI Support
Tune support for Stage 2 with Multi Port Injection upgrade
Check technical details for supported MPI injectors
Partnering with our friends from Turbo Concepts we utilized their MQB performance turbo (TCQ38600) which is capable of supporting 600 crank horsepower.
This turbo has the following attributes
PERFORMANCE TURBINE WHEEL
CERAMIC BALL BEARING
UPGRADED COMPRESSOR BILLET.MILLED COMPRESSOR WHEEL
LARGER A/R .73 TURBINE HOUSING
D5S CASTING MATERIAL
ALL INTERNALS UPGRADED PERFORMANCE 360 THRUST BEARING
LARGER INLET ADAPTER FOR DECREASING DEPRESSION
LARGER FLOWING COMPRESSOR COVER
VSR TESTED & PERFORMANCE BALANCED
To support this turbo we need to upgrade the fuel system, we installed MPI and Hellcat LP fuel pump. This recipe delivers outstanding top-end without sacrificing low-end grunt, the perfect daily driver powerband.
Our very own development S3 has gone 10.8 in the 1/4 on pump 93 with this setup, stock suspension and summer tires but capable of going faster when on Ethanol. It has achieved 10.69 on E20~ with a 1.59 60ft!
Stage 3 Tunes are available on InstaTune as Off-The-Shelf base map files. In most cases, these files will work as intended, but due to variations in local fuel, hardware discrepancies, and vehicle condition, data logging may be required to ensure the tune is working as intended. If you do not have access to the required fuel specified on InstaTune, you may request a tune revision for your local available fuel. This may also require data logging to ensure correct adjustments are made to your tune. Data logging is recommended (and in some cases may be required) to ensure customer satisfaction and engine longevity. Our goal is to provide you with the best tuning solution for your hardware setup.
We understand that our end users have varying driving styles and build purposes, which is why we offer custom tune revisions on all of our base maps. By offering custom tuning to our customers, we can be sure you are getting the most out of your vehicle. Our base 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 off the shelf bolt on upgrades.
