Stage One upgrade from Sportec for Audi S5 (3.0 TFSI version) includes sport air filter and ECU remap. The car is powered by 3.0 liter turbocharged petrol TFSI engine with 328 bhp. After the upgrade, the power plant develops whopping 425bhp at 6640RPM. This means an improvement of 97bhp, not bad at all.

The torque improvement is also significant – 80Nm. Audi S5 now produces 520Nm (379 lb-ft) at 4250RPM, compared to 440 Nm Nm (325 lb-ft).

Audi S5 Coupe and Convertible is equipped with 7-speed S-Tronic transmission, so there isn't any trouble with the power-up.

Stage One reflects astonishingly on the acceleration of the sports car – 0 to 100 km/h in 4.6 seconds and the top speed is limited at 155 mph (250 km/h) for safety reasons. However, without it, the car will probably hit the 300 km/h barrier.

The price is just ridiculous for such amount of power. Stage One from APS Sportec is priced at £1950 fitted including VAT.
