The IE Performance ECU Tune for the Audi F3 Q3 2.0T Gen 3 completely transforms your daily SUV into a sharp, responsive, and performance-focused crossover—without sacrificing comfort or reliability.

With gains of up to +91 horsepower and +81 ft-lbs of torque, your Q3 can produce up to 329 HP, delivering stronger acceleration, faster throttle response, and a noticeably more engaging driving experience. Best of all, flashing is completed at home in minutes using your phone, with no workshop visit required.

Engineered Performance, Your Way

IE’s advanced ECU calibration increases horsepower and torque across the entire powerband while maintaining factory-level drivability. With octane-specific maps for 87, 91, or 93 AKI fuel (91 / 95 / 98 RON), you can run your preferred fuel with no hidden power left behind.

This tune is fully compatible with:

• Completely stock vehicles

• Upgraded intake systems

• Turbo inlet upgrades

• Intercoolers

• Cat-back exhaust systems

A Complete Driving Transformation

This tune does far more than simply add power. IE’s calibration engineers completely rewrite the engine management system to refine how your Q3 drives in every scenario.

You’ll experience:

• Reduced throttle lag

• Linear, predictable power delivery

• Optimized boost by gear

• Improved engine and transmission communication

• Smoother throttle response

• Removed factory road speed limiters

The result is a Q3 that feels more connected, more responsive, and purpose-built for enthusiasts.

Raised Neutral & Park Rev Limiter

The factory “soft limiter” has been removed and replaced with a 7000 RPM neutral and park rev limit, giving you full throttle control when you want it—ideal for diagnostics, demonstrations, or motorsport use.

Full Power Without Compromise:

IE’s tuning philosophy prioritizes maximum safe performance. Every ECU parameter has been carefully reverse-engineered and expanded beyond factory limits while retaining and enhancing all critical safety strategies.

Extensive in-house testing is performed using advanced dyno systems—including IE’s proprietary sea-level simulation technology—to validate performance and reliability in all climates and elevations.

Whether commuting daily or driving through mountain passes, this tune delivers confidence-inspiring power everywhere you go.
