2009 - 2016 AUDI A4 A5 B8 B8.5 2.0t Ecu Tune (Remote)
Audi A4 / A5 B8 2.0T ECU Tune
Real Numbers. Real Pulls.
Tap a stage — power, fuel, and required mods at a glance. Crank figures on 93 octane, against the 210 HP / 280 TQ we saw stock on our dyno.
How It Works — Remote Tune
No shop visit. We flash your A4 / A5 over the internet while you watch it happen live on your screen.
Schedule — after purchase, book your remote flash session with BDT.
Set Up — Windows laptop with TeamViewer, our OBDII cable in the port, battery maintainer on the car, key in accessory.
We Flash It — BDT remotes into the laptop and runs the whole flash while you watch live.
Drive — key off on command, unplug, done. A few fault codes right after flashing are normal; they clear after a short drive cycle.
This ECU family flashes via a live BDT remote session. Self-flashing with the BDT Flasher lands when this platform is ported.

STG1 B8 a4
The car feels more alive, with stronger acceleration and a much more responsive throttle. Power builds smoothly and confidently, making everyday driving far more exciting. The turnaround time was impressive as well - everything arrived quickly and the process was simple from start to finish. If you're looking to wake up your 2.0T and unlock its true potential, this tune delivers.

Stage 1 intense burbs
The Stage 1 Tune for my 2009-2016 Audi A4/A5 B8/B8.5 2.0T delivered an excellent driving experience. Throttle response felt sharper, power delivery was smooth, and the overall performance improvement was immediately noticeable. The vehicle felt significantly quicker and more refined throughout the RPM range. Installation was straightforward, and I received the tune in under a week. Highly recommended for anyone looking to enhance their 2.0T's performance.

Trent is the man!
This was my first time dealing with Trent at Boost Dynamic. It's not too often you come across people in this trade or this line of business that go above and beyond and actually care about what they're doing and how they're doing it. Extremely knowledgeable and a pleasure to talk to. Dude knows his stuff. He got my Audi B8 2.0T build DIALED IN! Really impressed with Boost Dynamic and how they do things. Remote tuning is no easy task at all and he does it really well.
