2009–2015 Audi A4/A5 2.0T Stage 1 ECU Tune (B8 & B8.5)

Unleash the Full Potential of Your Audi A4/A5 2.0T

Your B8/B8.5 Audi A4 or A5 2.0T is capable of much more than factory numbers suggest. With Boost Dynamic Tuning’s Stage 1 ECU calibration, you’re not just unlocking horsepower — you’re transforming throttle response, turbo spool, and mid-range torque delivery. Whether you daily drive, carve backroads, or line up at the drag strip, our tune delivers repeatable power and razor-sharp response.

Proven Power Gains (Dyno Tested)

• Stock Advertised: 211 HP / 280 TQ
• BDT Baseline Dyno: 210 HP / 280 TQ
• Stage 1 93 Octane: 270 HP / 338 TQ

That’s a gain of +60 HP and +58 TQ on pump gas. All results are backed by dyno data — not estimates.

Whether launching from a dig or passing on the highway, power comes on instantly — no hesitation, just acceleration.
