Audi S5 B9 2.9TFSI Quattro MY2017 – #Etuners Stage2
Sounding more like a Tesla than a 3.0l turbo from the factory the owner requested a solution to give this S5 it’s soul back.
We chose to upgrade the downpipe to a hi flow ECS unit and leave the rest of the system OEM. With the addition of a custom Etuners ECU file and small exhaust modification, a 50kw gain @ all 4 wheels was made with power increasing to 250wkw.
Crackle on lift off was activated with an audible “fart “ on the shift. We now have one very happy customer!
- Maximum power at the wheels: 250wkw/340whp (measured stock at 201wkw/273whp), gains 49wkw/67whp
