In our latest dyno test we had this incredible 2025 Audi 8Y RS3 in for tuning and testing. We’ve already conducted extensive development on these, so already know what that 2.5 TFSI engine is capable of. After quick installation of our 3 channel module, it was up on the rollers to see what gains had been made.
This 8Y RS3 is also another example of the later VAG vehicles, which face the tuning limitations due to the locked ECU, and currently has no way to read or write the ECU data. This means that while traditional remapping is impossible, our tuning module offers the perfect solution here, providing fantastic gains without requiring a traditional ECU flash. This has the added benefit of being traceless once removed for warranty purposes.
Dyno testing before and after shows healthy gains across the rev range, with a significant increase in power and torque, really transforming how it feels to drive.
Peak power was significantly increased, as we were able to lift it from 404hp at stock, up to 463hp with the box. If you take a look at the dyno graph below you can see how we change that curve (dotted red and blue lines). We give real consistency here, bringing that extra power in as soon as possible, whilst holding it for as long as possible throughout the entire rev range, adding that +59hp at its peak, really transforming how it feels out on the road.
Torque also saw some really impressive improvements. At stock the engine produced 529Nm and now 608Nm with the box. If you take another look at the graph (solid lines), you can really see where we have applied those gains. Again looking across that whole portion of the mid-range, you can really see exactly where its lifted, adding the +79Nm extra at its peak, delivering that increase exactly where it’s needed.
