Audi RS6 and RS7 both utilise the latest and most powerful turbocharged 4 liter TFSI engine with 8 cylinders and 32 valves in total. Twin turbos make this engine produce twice the power of two individual 2.0 TFSI Golf Rs.

This Audi RS6 C7 came to us with an existing custom tune from another tuner. On our Dyno Dynamics rolling road, it produced peak power of 383wkw, tuned as it came in. After custom remapping with an Etuners stage2 calibration, the peak power rose to 422wkw. A gain of 39wkw over the previous tuners file. An impressive 70wkw gain in the midrange was made, totally transforming the car.
