BDT Stage 2 ECU Tune

Audi A6 2.0T TFSI (C7/C7.5)

Our Stage 2 Tune is everything you’ve been looking for to wake up the potential of your 2.0T A6. This is the setup where the car stops feeling “quick”… and starts feeling dangerous. Faster spool, stronger mid-range torque, and a pull that stays clean through the powerband — all while keeping drivability and OEM-style safety logic intact.

Be ready for a reliable everyday commute… or a launch down the drag strip at any time!

Fitment & Compatibility

BDT Stage 2 Tune Features

Stage 2 quick summary: the torque hits harder, spool comes faster, and the car pulls longer — because the exhaust can finally breathe.

• Increased horsepower and torque gains with proper exhaust flow
• Speed limiter removed
• Neutral/Park rev limiter raised (where supported; TCU tune recommended)
• Torque limiters raised
• Fueling requested changed (depending on throttle position)
• Optional Overrun/Crackle (Dynamic mode)
• Boost control refined for a linear boost onset
• Turbocharger lag reduced / improved response
• Low pressure fuel pump pressure increased
• High pressure fuel pump pressure increased
• OBDII port flashing

2.0T A6 Stage 2

Boost Dynamic Tuning’s Stage 2 ECU calibration methodically increases performance with gains up to 300 HP & 360 TQ, without any sacrifice in drivability or reliability. BDT’s calibration design efficiently and safely maximizes the factory turbo’s potential with OEM-style safety strategy.

Crackle Pops (Overrun)

Also known as overrun. When decelerating from higher RPMs (or free-revving in neutral/park), you’ll hear controlled pops from your exhaust/downpipe. Subtle on quiet setups — louder on freer-flowing exhaust. Tuned with RPM windows + safety logic to keep it fun and controlled.

Boost Control

Factory boost delivery can be bumpy and uneven during long pulls. BDT Stage 2 refines and smooths the boost curve so power comes on harder, cleaner, and stays consistent through the pull.

Power Gains

Expected Stage 2 gains (93 octane): up to 300 HP and 360 FT-LBS. Results vary with dyno type, altitude, weather, fuel quality, and supporting hardware.

ECU Tune Modification Requirements

Stage 2 hardware (quick view): A high-flow downpipe / exhaust flow upgrade is REQUIRED. Intake + intercooler are recommended for consistency and heat control. TCU tune is highly recommended where equipped.

Software Installation Requirements

WINDOWS LAPTOP REQUIRED (NO APPLE)
