O.CT Tuning has a new compressor kit that dials up the noise on the standard Audi R8 to a GT-like level. With the "Black Compressor" system, coupled with an ECU optimization and a stainless-steel exhaust, output is boosted on the 4.2 liter V8 (with a standard 420 PS / 309 kW / 414 bhp) up to 565 PS (416 kW / 557 bhp) and 560 Nm (413 lb-ft) of torque. The R8 GT and GT Spyder models feature 560 PS (412 kW / 552 bhp) and 540 Nm (398.28 lb-ft) of torque.

O.CT Tuning also cordially lifts the V-max limiter on the R8 and allows the car to reach that previous 250 km/h (155 mph) limit in only 24 seconds. The 0 to 100 km/h (62 mph) sprint is also improved upon by 0.7 second over the series car.
