An all new performance tuning package has been released for the Audi TT-RS by the company B&B. There are four different tuning stages available for the new Audi, all resulting with impressive power numbers. The Stage 1 kit consists of a simple ECU tuning to take the boost level up an extra 0.2 bar, giving the engine 410 hp and priced at 1,950 euro. In the Stage 2 package, customers receive an extra 0.25 bar of boost along with an upgraded cooling system, resulting in 425 hp for 2,950 euro. The third stage is a bit more expensive than the first two, but the performance increases are well worth it.
In the Stage 3 kit, B&B hooks up the Audi TT-RS with a new stainless steel exhaust along with extra engine tuning to bring the car to 442 hp and 625 Nm of torque for 8,950 euro. The final stage, or the Stage 4 performance package includes all the above previously mentioned, a larger air filter, and for 12,950 euro the Audi is boosted to 450 hp and 640 Nm of torque. With the maximum horsepower at 450, the TT-RS model can sprint from 0-100 km/h in 3.7 seconds. Also included in the tuning kit are 19 or 20-inch rims, high performance braking system, aero styling parts, and a suspension kit. The lowering springs drop the Audi TT-RS 20 mm closer to the ground to improve handling and stability.[Source: carsroute]
