German electronics expert Mcchip-DKR got a custom Audi S4 Avant in their workshop in need of a power boost. So they uploaded their magical software into the car’s ECU and strapped it on the dyno machine to see what they have achieved.
What they had achieved was truly astonishing. The standard Audi S4 Avant 3.0 liter TFSI is a fairly powerful wagon boasting 333 PS and 440 Nm of torque as standard. After Mcchip is through with the car, those numbers go up to 422 PS and 514 Nm of torque.
That is a huge gain for a mod that is essentially a few lines of code. It goes to show the potential of these TFSI engines for upgrade. If you can do this only with software, what more can you achieve with, say, bigger turbos, or custom exhausts and manifolds?
Mcchip has not announced any performance numbers for this beefed-up Audi S4 Avant, but the standard car accelerates in 5.0 seconds from zero to 100 km/h (62.14 mph) and achieves an electronically limited maximum speed of 250 km/h (155.34 mph). You could expect the tuned version to be around 15 percent quicker.
