The guys from DTE Systems have delivered a chip tuning for the current Audi RS3 Sportback. As you know, in standard, the German model is able to deliver 367 horsepower and 465 Nm peak of torque thanks to a turbocharged 2.5-liter engine. 

But these guys managed to squeeze another 43 horsepower and 92 Nm peak of torque out of that engine for a grand total of 410 PS (301 kW) and 557 Nm (411 lb-ft) of torque.

As a result, the Audi RS3 Sportback is able to run from 100 to 160 km/h with 1.1 seconds less than the previous stint. The improvement was achieved by implementing the PowerControl SNT module connected to the central sensors of the engine management system, turbo pressure, and intake manifold.
