Boost Dynamic Tuning does not sell, broker, or supply motor vehicles. Vehicle names, model years and photographs are used solely to identify which car this software is compatible with.

Pick Your Stage

Filmed pulls with a Q8 3.0T strapped to our AWD dyno — every number here is at the wheels, not the crank. Tap a stage to select it and check out.

Stage 1
362WHP
+61 WHP · +126 WTQ
91/93 octane · no hardware required
Select & Buy
Stage 2
373WHP
472 WTQ · with exhaust & FMIC
93 octane · high-flow exhaust & FMIC
Select & Buy

Stage 1 needs nothing but the file and hands back +61 WHP and +126 WTQ on stock hardware. Stage 2 only pays off once the exhaust and FMIC are already on the truck. Text us your build and we’ll tell you straight.

If your tuner doesn't show before & after dyno videos, you're being lied to.

A dynamometer is a before-and-after measuring tool — not an absolute output number. What can't be faked is the delta: same platform, same dyno, stock vs tuned — on camera, in the videos below.

 

How It Works — Remote Tune

No shop visit. We flash your Q8 over the internet while you watch it happen live on your screen.

1

Schedule — after purchase, book your remote flash session with BDT.

2

Set Up — Windows laptop with TeamViewer, our cable in the port, battery maintainer on the car, key in accessory.

3

We Flash It — BDT remotes into the laptop and runs the whole flash while you watch live.

4

Drive — key off on command, unplug, done. Fault codes right after flashing are normal and 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.

Your ECU Is Safe

Your stock file is savedWe read and archive your factory file before a single byte is written. You can flash back to stock at any time, free.
Verified writes, safe abortsEvery flash is checksum-verified. If the connection drops mid-write the process aborts safely and can be resumed — it does not leave your ECU half-written.
You talk to the calibrator11+ years of in-house VAG calibration. The person who built your file is the person on the phone — not a reseller passing on someone else’s tune.
