Audi RS4 B7 ECU Remap by mcchip-dkr

The Audi RS4 B7 generation (this is the previous one) might be gone from under the spotlights, but on the street, a ride like this still brings you a lot of respect, which is why the tuning world holds a special place for it.

The latest aftermarket developer to play with a B7-generation comes from Germany (of course): mcchip-dkr has remapped the ECU of the car. The 4.2-liter direct-injected, naturally-aspirated V8 powerplant of the car, which produces 420 hp and 430 Nm (317 lb-ft) when it leaves the factory, now delivers an extra 14 hp and 17 Nm (12.5 lb-ft).

The aforementioned increase might not sound like much, but we have to take into consideration that the ECU remap was the only mod used for the high-revving, naturally-aspirated engine of the go-fast sedan.
