Audi TT 225 in with us today for Stage 2 ECU tuning 🔥

This one put up a bit of a fight — none of our 4 tuning tools could communicate with the ME7.5 ECU via OBD, so the ECU had to come out and be read & flashed directly in boot mode instead. 💻🔧

A little more involved than usual, but we got it done. ✅

Had this stunning 2023 Audi RS6 in with us at the beginning of the week for our Stage 1 ECU & TCU tuning package. 🔥

As this model is fitted with the latest ECU protection, we first sent the ECU to Autotuner for unlocking. Once it was back, we bench flashed our custom Stage 1 ECU calibration before carrying out the TCU software upgrade via bench access from underneath the vehicle.

📈 Performance Gains:
⚙️ Factory: 600bhp / 800Nm
🚀 Stage 1: 720bhp / 950Nm

The result is a huge increase in performance, sharper throttle response, stronger mid-range pull, and faster, crisper gear changes thanks to the TCU calibration.

If you’ve got a late-model RS6 and want to unlock its full potential, get in touch to discuss your options.
