From the article:
The Audi RS3 in its standard configuration is a 367 PS & 465 Nm five-cylinder brute thanks to a turbocharged 2.5-liter engine, but DTE Systems has applied its chip tuning knowhow to squeeze more power. They were able to extract an additional 43 PS (32 kW) and 92 Nm (68 lb-ft) for a grand total of 410 PS (301 kW) and 557 Nm (411 lb-ft) of torque.
