Mod the New Audi TT-RS ECU and Push it to 400hp!

That's exactly what Mcchip did. Mcchip is a German tuner that specializes in modifying vehicle's ECU and engine management systems. The standard 2.5L turbocharged Audi TT-RS produces 340hp and 325lb-ft of torque. Mcchip can tweak the ECU to produce 380hp or 400hp and the torque can see a bump up to 406lb-ft. Pretty impressive for a 2.5L engine.

With this extra boost in power, the Audi TT-RS can reach a top speed of 186mph (31mph faster from stock) and run 0-62mph in just 4.1 seconds (0.5 seconds swifter).

Wondering how much a retweaked ECU is going to cost you? How about €899 ($1,275)! If you are looking for a few other modifications, Mcchip is also offering 20-inch custom alloy wheels from Cargraphic that sell for €6,600 ($9,357), as well as an adaptive shock absorber system that will cost around €1,100 ($1,600).
