BDT Stage 1 ECU Tune — 2015–2019 Audi A3 2.0T AWD (MQB • EA888 Gen 3 • IS20)

Your A3’s 2.0T is sitting on untapped potential — and our Stage 1 ECU Tune is the first step to waking it up. With Boost Dynamic Tuning’s custom calibration, you’ll unlock up to 345 HP and 390 TQ while keeping factory-level reliability and daily comfort. Remote OBDII flashing makes install plug, flash, and gap — no stress, no downtime.

 Be ready for smooth commutes, hard pulls, or a dragstrip launch at any time.


BDT Stage 1 Features

  • Horsepower & torque gains up to 345 HP / 390 TQ
  • Speed limiter removed
  • Neutral/Park rev limiter raised
  • Torque limiters unlocked
  • Overrun crackle in Dynamic mode
  • Refined boost curve for linear, responsive power
  • Turbo lag reduced — sharper throttle response
  • LPFP & HPFP pressure strategies increased
  • Multi-Map Switching (up to 5 maps on the fly)
  • Rolling Anti-Lag for instant spool
  • 2-Step Launch Control (Manual transmission only)
  • OBDII Port Flashing — no ECU removal

Why Stage 1?

BDT’s Stage 1 calibration methodically squeezes every ounce out of the IS20 turbo, delivering crisp throttle response and brutal mid-range torque. Perfect for the guy who wants more spice on the daily — and the power to leave “faster” cars embarrassed on a weekend run.

Crackle Pops

Add flavor to your exhaust with overrun pops. Subtle on stock pipes, violent on downpipes. Gunfire vibes at your command.

⚡ Smooth, Relentless Boost

Factory boost mapping feels uneven and laggy. Our Stage 1 refines the curve for a linear, silky powerband that stays pinned from gear to gear.

 Multi-Map Switching

Toggle up to 5 maps while driving using factory cruise controls. Daily, spicy race fuel, valet — you decide. (Not available on certain 2017 FWD models).

2-Step / Anti-Lag / Launch Control

Manual guys get rowdy: a secondary rev limiter (~4500 RPM) lets you build boost at launch for violent takeoffs and rolling anti-lag keeps your turbo lit.

Stock (Audi Advertised) 210 HP 258 FT-LBS

Why BDT Stage 1?

Smooth enough for your 9-to-5, mean enough for midnight pulls. This is the first step toward unleashing your Audi’s real personality. Boost Dynamic Tuning makes sure you enjoy it every time you push the pedal.

    Would highly recommend! Very easy to follow instructions and was relatively quick to tune. Made my car feel more sporty and my fuel economy even went up 10 or so mpg!
