The powerplant has seen its output increased from a dyno-measured 338 hp to 401 hp, with a maximum power gain at 63 hp at 5,989 rpm.
As Superchips likes to offer driveability and user-friendliness for the vehicles it tunes, the company has raised the 2.5 liter unit’s torque from a measured 466Nm to 551 Nm. More important, the ECU remap allows the engine to offer over 500 Nm of torque between 2,500 and 5,700 rpm.
The tuner has not release the performance data for its version of the TT-RS, only announcing that the 155 mph electronic speed limited has been kept. We have to remind you that the factory stock TT-RS deals with the 0 to 62 mph (100 km/h) sprint in 4.6 seconds.
Superchips claims that the power and torque premium hasn’t made the engine thirstier, allowing it to return the same average cycle fuel consumption of 9.2 liters/100 km ( 30 UK mpg or 25.5 US mpg).
“Audi TT RS owners can also be reassured that the Superchips ECU remap delivers a minimal fuel consumption penalty. Indeed if driven in a ‘like for like’ manner with the standard car, owners will experience no fuel consumption penalty, despite the extra performance,” stated the press release.
In addition to that, the conversion can be a DIY operation, as it is offered through the company's bluefin ‘plug and go’ handset, which also allows the original Audi ECU map to be stored and reinstalled subsequently, also as a DIY operation.
