Austrian tuner Oberscheider Tuning (O.CT) has a performance package for the Audi TT RS that can squeeze even more power from its 2.5 liter, 5-cylinder TFSI engine.
The conversion kit for the power upgrade includes new hardware components (such as the charge air cooler kit) along with an ECU remap that dials output up to 420 PS (309 kW / 414 bhp) and 570 Nm (420 lb-ft) of torque from the series' 340 PS (250 kW / 335 bhp) and 450 Nm (332 lb-ft). Also helping boost the power rating is a stainless-steel exhaust system with silencer and an additional valve-controlled rear silencer.
O.CT also adds a set of 9 x 20-inch (ET35) alloy wheels in a twin-spoke design which weight just shy of 14 kg each.
The tuner provides a KW V3 coilover suspension kit to help handle the extra go on the road.
