MTM Boost Audi TT-RS to 424bhp

German tuner MTM has launched a performance package for the new Audi TT RS. Under normal circumstances the car produces 340hp (250kW) of power and peak torque of 450Nm (332 lb ft) between 1,600rpm and 5,300rpm. The factory claims a 0 - 100 km/h time of 4.6 seconds.

MTM used the stock 2.5-litre 5-cylinder turbo as a basis. The engine control unit was adjusted and a new exhaust system with new middle- and end- pipes with throttle valves fitted. Not only does it apparently sound great, but it also revs higher and accesses its torque across a wide range of revolutions.[via]
