German tuner mcchip-dkr has developed an upgrade package for the defunct Audi TT RS. Most of the work was on the five-cylinder, 2.5-liter turbocharged gasoline engine which in standard configuration develops 340 PS (250 kW) and 450 Nm of torque, but the tuner was able to bump the output to no less than 473 PS (348 kW0 and 610 Nm. It was all possible thanks to software optimization, a revised turbocharger as well as a custom exhaust system with sport cats and downpipes.
They haven’t messed around with the car’s design as this Audi TT RS look just about the same as the standard model but underneath the familiar skin is a much more powerful car which has even more power than the TT RS Plus and the V8 4.2 FSI.
Audi has already confirmed a new TT RS is on its way and will retain the 2.5-liter 5-cylinder motor now installed in the RS3 Sportback where it generates 367 PS (270 kW) and 465 Nm. Chances are the TT RS will come with revised power figures to differentiate the model from the RS3.
