BDT Stage 1 ECU Tune – Audi A4 B7 2.0T (2005–2008)

Unleash the full potential of your turbocharged Audi A4 B7 2.0T with Boost Dynamic Tuning’s Stage 1 ECU calibration. Designed for daily reliability and engineered for maximum performance, this tune delivers sharper throttle response, faster turbo spool, smoother boost control, and real-world power gains you can feel instantly.

At BDT, all calibrations are developed in-house—no generic maps, no shortcuts, no guesswork. Our tunes are dyno-tested, street-refined, and built from over a decade of hands-on experience with the EA113 2.0T FSI platform.

Stage 1 Features

• +80 HP / +95 TQ gains (when combined with healthy hardware)
• Speed Limiter Removed
• Raised Rev Limiter in Neutral/Park
• Raised Torque Limiters
• Refined Fueling Strategy
• Optional Crackle/Overrun (Low, Medium, Intense/Flames)
• Linear Boost Onset & Smoother Control

Crackle Pops (Overrun)

Add personality to your exhaust note with our optional crackle/overrun feature. When decelerating or free-revving, you’ll hear crisp pops and crackles—subtle on a stock exhaust, aggressive with an aftermarket setup. Tuned safely and controlled for longevity.

Boost Control Refinement

The factory boost control strategy on the B7 A4 delivers a rough, inconsistent curve that causes lag and hesitation. Our Stage 1 tune smooths boost delivery across the entire RPM range, giving you instant throttle response, predictable power, and strong acceleration in every gear.
