BDT Stage 3 ECU Tune
2016–2023 Audi TTS (8S • 2.0T MQB • EA888 Gen 3)

Sound + Control
Stage 3 isn’t just about peak numbers — it’s about control: boost behavior, torque delivery, and safety strategies that keep the car consistent pull after pull.
Crackle Pops — The Overrun You’ve Been Waiting For
Add serious auditory character to your TTS with controlled overrun/crackles — perfect for enthusiasts who want that aggressive sound on decel or revs in Neutral.
- Controlled & safe implementation
- Active only in Dynamic/Sport Mode
- Sharper pops with freer-flowing exhaust setups
- Automatic safety reduction if exhaust temps climb too high
⚙️ Boost Control Recalibrated
The factory TTS 2.0T boost curve can feel conservative and inconsistent once you’re on a turbo upgrade. BDT rewrites the boost logic to deliver:
- Smoother, more linear boost ramp
- Instant throttle engagement
- Consistent power delivery through every gear
This isn’t just tuning — it’s precision-built calibration that transforms the way your TTS drives.
Built for the Streets. Proven on the Dyno.
Whether you’re hunting apexes or showing out at a local meet, BDT’s Stage 3 ECU Tune gives your Audi TTS the balance of refined daily comfort and raw performance when you get into it.
Don’t just drive your TTS — dominate in it.
