Is this a staged map or a custom tune for the Volkswagen Jetta GLI?

Both. Our Staged maps are ready-made, off-the-shelf Stage 1 and Stage 2 calibrations you configure and flash yourself. Custom is a fully bespoke tune built around your exact hardware and fuel, with a revision loop and lifetime support.

Do you offer a Stage 1 map and a Stage 2 map for the Volkswagen Jetta GLI?

Yes — Stage 1 (factory hardware) and Stage 2 (intake, intercooler, downpipe) are both configurable, in Staged or Custom form, for the 2.0T IS20.

Is this a remote tune or do I need a dyno?

100% remote, anywhere in the world. You flash the file at home with the eFlash dongle and we review your datalogs remotely — no shop visit and no dyno appointment.

What else is this called?

Depending on who you ask, an ECU tune is also called a remap, a Stage 1 / Stage 2 map, a staged tune, a performance map, a power map, a race tune, mapping or chiptuning. This is that product for the Volkswagen Jetta GLI.

Advanced Information

Stage 1 Tuning

Stock Hardware — A Stage 1 ECU tune will safely harness more power and torque while still using stock hardware.
Fuel — We improve the power output with all grades of premium fuel and ethanol while retaining the OEM hardware lifespan.

Stage 2 Tuning

Optimization for intake, intercooler & downpipe for efficiency: With changes to the Intake, Intercooler and Downpipe, we can free up tremendous amounts of airflow and volume resulting in cooler charged air, lower back pressure, and more power.
- Intake — The factory intake is designed for silent operation and prioritizes that over performance. With an upgraded intake and an increase in airflow, we improve throttle response and make more power.
- Intercooler — A larger intercooler will be able to cool the charged air more efficiently with increased boost pressure for consistent power delivery.
- Downpipe — Increased flow (typically from a hi-flow catalytic converter) and subsequent lower backpressure allows the engine to breathe easier
Fuel — We improve the power output with all grades of premium fuel and ethanol while retaining the OEM hardware lifespan.

Custom Tuning for Engine & Transmission

Log based tuning specific to your vehicle and goals: Every vehicle is different, even with stock hardware from the factory which is why modern vehicles have advanced logic and control systems in place to compensate and accommodate the changes between different vehicles.
Stock or upgraded hardware
- Turbochargers
  - Stock turbo — While our Staged tunes are a great fit for these cars, additional modifications such as turbo inlets or larger intakes as well as straight piped exhaust with complex intake setups can take the setup out of the acceptable range where a “one-size-fits-all” tune can accommodate. A Custom tune is also a great option for stock and upgraded hardware to properly optimize the overall boost control, fueling and behavior to your specific liking
Street or track: Dial in your car to the specific setup and application with changes like shiftpoints, launch control and overall power delivery

Transmission Tuning

The stock transmission calibration (tune) prioritizes comfort and efficiency at the expense of responsiveness and driving pleasure.
- Shift speed increased
- Increased clutch pressure and rescaled torque limitations
- Redline shift points raised
  - Standard auto-upshift in M/Tiptronic (optionally disabled)
- Optional shift point optimization for Comfort and Dynamic/Sport drive modes with OEM+ or OEM++ calibrations for all Staged Transmission Tunes
- Improved launch control with the 200 launch limit removed
- Enhanced clutch cooling strategy
- Gear display enabled in Drive/Sport/Tiptronic (D/S/M) - Vehicle and box code dependant
- Standing rev limit in park/neutral raised to 6000 rpm (requires matching engine tune)
