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
Ethanol Sensor
Required (For Flex Fuel Files)
High Pressure Fuel Pump Piston Upgrade
DSG tune is recommended to optimize shift patterns and increase driver enjoyment in Sport and Drive modes

*See hardware requirements for Flex Fuel compatibility
New Features
Function
Recalibrated Performance Monitor
OEM Boost gauge is re-calibrated to show actual boost pressure
Power Request monitor is re-scaled for our power increase
On/Off Crackles
Exhaust Crackles can be turned on/off in any Drive mode using cruise control buttons
Ethanol Gauge
Monitor Ethanol Content using cruise control buttons. Ethanol content is displayed using the Tachometer (eg. 5500 RPM = E55%)
*Ethanol Sensor must be installed to use this feature.
Flex Fuel Tune
True Flex tune is compatible with Stage 1 and 2 files.
*Requires High Pressure Fuel Pump Piston Upgrade and Ethanol Sensor
Power output adjusts with ethanol content.
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
Boost by Gear
Gear dependant boost settings
Used for Torque management (traction) on FWD vehicles
Can be used as a clutch saver tune for Manual vehicles
Minimum 91 Oct / 95 RON fuel
Highly Recommended
Highly Recommended (Required for Flex Fuel Files)
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
For Stage 2 vehicles wanting to add Multi-Port Injection to their vehicles, TuneZilla now offers MPI support on Stage 2. This fuelling upgrade allows owners the flexibility of future upgrades and raises the ceiling of the potential power output by adding 4 more injectors into the intake. A low pressure fuel pump upgrade is required as well. MPI Files are not available on Instatune, you will need to make a Tune Request in the TuneZilla Portal App.
Hardware Upgrade
All Stage 2 Requirements
Required As Above
MPI Fuelling kit (980cc injectors)
Hellcat 525/535 LPFP
Recommended (Required for Flex Fuel support)
Flex Fuel is made possible with Stage 2 by upgrading the fuelling system and adding an ethanol sensor. Benefits of ethanol is the cooling effect it has on the intake air temps. Lowering risk of knock, more efficiency during combustion, and the ability to advance timing even further to produce more horsepower. The true flex fuel tune allows the vehicle to self adjust based on the ethanol content in your fuel. Simply add E85 to your tank and let the vehicle do all the math to adjust timing and boost.

This Stage 3 IS38 tune is optimized to use the stock fuel system. 93 Octane is required.
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.
Increased Rev Limiter
Adjust timing to optimize high-octane fuel
Adjust boost request values
Increase throttle response for improved pedal feel

For Stage 3 vehicles wanting to add Multi-Port Injection to their vehicles or upgrade to Flex Fuel tunes. This fuelling upgrade allows owners the flexibility of future upgrades and raises the ceiling of the potential power output by adding 4 more injectors into the intake.
