We had the pleasure of tuning an exceptionally clean Audi RS3.
Sometimes they come in with pages of faults.
Sometimes they come in needing rescued.
This wasn’t one of those.
The brief was simple — healthy car, sensible gains, done properly.
It flew through the vehicle health check. No hidden surprises. No stored gremlins. Just a solid base to work from. The only thing we picked up? The ECU and DSG were running older software versions. Not a problem, but not ideal either. So before we even thought about tuning, we updated both to the latest factory software - free of charge. If we’re building on it, it’s getting built on the right foundation.
Once everything was up to date, we moved onto the custom Stage 1 ECU and DSG calibration.
The DQ500 gearbox responded beautifully. Fast, decisive shifts. No hesitation. No flare. Just clean, aggressive changes exactly how an RS3 should feel.
On the engine side, we took it from 367bhp to a healthy 420bhp and 620Nm of torque. Strong, smooth, and relentless through the mid-range.
No drama.
No inflated numbers.
Just a properly set up RS3 done the right way.
