Every SQ5 figure below is a filmed pull on our AWD dyno — not a brochure claim. Tap a stage to select it and jump to checkout.

Not sure which stage? Stage 1 bolts onto a completely stock SQ5, and Stage 2 only asks for a high-flow exhaust. Text us your setup and we’ll point you at the right one.

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 SQ5 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 OBDII 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. 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.

    Stage2 Remote Tune

    Posted by Julien Murillo on Jul 11th 2024

    This product was absolutely amazing! I got my 2019 SQ5 Stage2 tuned the other day and it performs even better than expected! I added the extra Intense/Flames Crackle Pop Tune, and it DID NOT DISAPPOINT!!! The amount of pops and crackles it spits out is insane. If you keep it around 3,000rpm while cruising with your foot off the pedal it’ll just keep going. This Tune Went Above and Beyond My Expectations, 10/10 Definitely Recommended!!!
