Volkswagen Tune

Get a professional Volkswagen ECU tune from Viezu USA — more torque, sharper throttle response, and better overall drivability from a calibration built for your specific platform. The VW EA888 TSI engine is one of the most tune-responsive platforms on the market, and our TDI diesel tunes are purpose-built for real-world performance and efficiency gains.

Select your model, engine, year, and tune type below. Your vehicle-specific add-on price will be reflected at checkout.

What's Included

• Custom ECU calibration built for your specific engine and platform

• Dyno-documented results (in-house flash)
• Clear communication on turnaround time and expectations
• Follow-up support if adjustments are needed

Tune Types Available

Stage 1 — OBD Tune
No hardware modifications required. Tuned directly through the OBD port. The most accessible and popular entry point for VW TSI platforms. Significant power and torque gains on GTI, Golf R, Jetta GLI, and Tiguan without touching a single bolt.

Stage 2 — Supporting Modifications Required
For vehicles running upgraded intake, exhaust, intercooler, or other hardware. Stage 2 extracts everything your modifications have to offer with a calibration built around your exact setup. Contact us before ordering to confirm your build is Stage 2 ready.

Economy / MPG Tune
Optimized for fuel efficiency without sacrificing drivability. Particularly effective on the 1.4L and 1.5L TSI platforms and VW TDI diesels. A practical option for daily drivers and commuters looking to stretch their fuel budget.

TDI Diesel Performance Tune
Purpose-built for the 2.0L TDI and 3.0L TDI V6 platforms. Improved torque delivery, better throttle response, and stronger pulling power — without compromising the reliability VW diesel owners depend on.

TDI Diesel Economy Tune
Calibrated specifically for fuel economy on TDI platforms. Real-world MPG improvements for daily drivers and high-mileage commuters.
