2009 - 2016 Audi A4 A5 B8 B8.5 2.0t Stage 1 Tune

Unleash the Full Potential of Your 2009–2015 Audi A4/A5 2.0T (B8/B8.5)

Exclusively Tuned by Boost Dynamic Tuning — Performance Without Compromise

Your Audi’s 2.0T is capable of so much more than the factory allows. With BDT’s Stage 1 ECU calibration, you’re not just unlocking horsepower — you’re transforming the entire driving experience. Whether you’re commuting, carving backroads, or lining up at the drag strip, our tune delivers razor-sharp throttle response, instant turbo spool, and torque that hits like a freight train.

With over 12 years of tuning experience and all calibrations built in-house, we don’t guess, copy, or outsource — we test, refine, and perfect. Every file is backed by real dyno data, ensuring you get exactly what we promise: authentic, repeatable power with zero compromise on reliability.

Why Choose BDT?

• Proven Gains: Up to 270 HP / 338 TQ on pump gas

• Built In-House: No generic maps, no resellers

• Street & Strip Ready: Refined for both daily driving and hard pulls

• Remote Convenience: Flash your tune via the OBDII port — no shop visit required

• Passion Meets Precision: You will get to talk directly to your tuner, no some sales guy! 

BDT Stage 1 Highlights

• Optimized Boost & Torque Delivery

• Speed Limiter Removed

• Torque Limiters Raised

• Neutral/Park Rev Limiter Raised 

• Sharper Throttle Response & Reduced Turbo Lag

• Increased LPFP & HPFP Pressure

• Overrun/Crackle in Dynamic Mode

• Linear, Predictable Powerband Across All Gears

• Flashable via OBDII — No Physical Mods Required

Crackle Pops (Overrun Feature)

Make your Audi sound as good as it feels. When decelerating from higher RPMs or free-revving in Neutral/Park, you’ll hear sharp, addictive pops and crackles from your exhaust/downpipe. Subtle on stock systems, wild with an aftermarket setup — it’s the perfect blend of aggression and control.

Boost Control Optimization

Factory boost delivery is bumpy and inconsistent, especially in long pulls.
BDT’s Stage 1 calibration smooths the curve for:

• Faster spool

• Linear boost onset

• Consistent power across the entire powerband

Whether you’re launching from a dig or overtaking on the highway, power comes on instantly — no hesitation, just acceleration.
