Stop leaving power on the table. Elevate your driving experience with BDT’s Stage 1 Q5 tune — crafted exclusively for your 2021–2025 Audi Q5 45 TFSI.

Crackle Pops / Overrun (Dynamic Mode Only)

Bring your Audi to life with our overrun/crackle calibration — a crowd-favorite feature that adds drama and personality to every drive.

When decelerating from higher RPMs or free-revving in Neutral/Park, you’ll hear sharp, exhilarating pops and crackles. It’s a controlled and safe enhancement designed to deliver an aggressive sound profile that turns heads — especially when paired with an aftermarket exhaust.

Note: Effect may be more subtle on stock exhaust systems. Safety logic reduces crackles if exhaust temperatures rise excessively.

⚡ Boost Control Optimization

From the factory, the stock ECU delivers a rough and inconsistent boost curve. BDT Stage 1 refines boost control for clean, confident pulls every time.

• Smoother, more linear boost delivery
• Sharper throttle response
• Consistent power across the entire powerband

Maintenance Schedule (Required for Tuned Vehicles)

IF YOU WANT YOUR CAR TO SURVIVE, THESE MUST BE DONE!

I want your Q5 to survive multiple years with my tune. This isn’t optional — it’s what keeps the EA888 hybrid reliable under added load. If you can’t afford the maintenance, please don’t tune the car.
