MY2014 Audi RS7 C7 4.0TFSI
A base Dyno run was performed with custom upgraded downpipes. no other hardware upgrades, showing 351wkw.
We installed a water meth kit and custom Etuners Stage2 ECU calibration and Etuners Stage2 gearbox remap, increasing midrange power by +125wkw and peak power to 452wkw.
The RS7 C7 is equipped with a ZF AL551 gearbox unit with 8 gears, capable of withstanding 735kw (1000hp) and 1000nm. Unless the gearbox software is modified, it causes restrictions to the car’s power output. Reflashing it allows us to remove the torque and LC limitations from the TCU. We were also able to speed up the gear shifts and increase the rev limiter, so that the engine is always in its optimum efficiency range.
