Audi TT RS with 551 Nm by Superchips

Powered by five-cylinder 2.5-litre turbocharged direct injection TFSI engine coupled to Audi’s trademark quattro four-wheel drive system, the TT RS is anything but slow.

In fact, it’s the most powerful TT Audi has ever built, but according to Buckingham based performance electronic experts Superchips it’s not quite fast enough.

After a detailed remap of the TT RS’s Bosche ME9 ECU by the Superchip wizards, power is up from 252 kW to 300 kW and torque rises from 466 Nm to 551 Nm.

Not convinced? Did I mention that 500 of those Newton-metres are available between 2500-5700 rpm?

These are substantial upgrades, which should see an increase in acceleration over the standard 4.7second 0-100km/h sprint time, but it begs the question of reliability and general day-to-day usefulness around town.

Superchips are quick to point out that their ECU remaps place a strong emphasis on drivability and user friendliness and the TT RS project is no exception. Hence, the factory spec top speed of 250km/h has been left unchanged for safety reasons.

The company also says that if the car is driven in a ‘like-for-like’ manner with the standard TT RS, then owners should see no change in the car's fuel consumption, despite the extra performance.

The actual implementation of the ECU remap does not need any particular skill set and is simply a matter of plugging a bluefin handset into the Audi TT RS’s OBD11 port and following the on-screen instructions.

The original factory settings are also stored on the handset and can be restored to the car in a matter of minutes, says Superchips.

The cost of the Superchips remap is £445 and is available from any of the 100 dealers in the UK.

The company also covers the car with a customer service guarantee and a full 12-month/30,000 kilometer supplementary warranty.
