That’s right, the flat black Avus Performance tuned Audi TT-RS makes a total of 460 HP and 471 lb-ft of torque with only a few minor tweaks to the factory ECU as well as a new free flowing exhaust system. This is an extremely simple procedure considering that not too long ago the parts list would have included: a set of bump sticks, valve springs and possibly some nitrous. The simple performance upgrade is good to bring the stock car’s 4.6 second 0 to 60 MPH time down to 3.8 seconds and raise the TT-RS’s top speed from 178 MPH all the way up to 193 MPH, bringing it even closed to super car status. When the Audi Sport Quattro was born it too produced a mere 300 HP, but by the time that Group B was banned the fire breathing Ur-Quattro was making somewhere closer to 650 HP. Now we may not see gains like those in the immediate future from a reflash and some new pipes, but don’t tell that to any of these high performance Audi tuners.
