Audi S8 4.0 TFSI

We like Audi S8 4.0 TFSI! The performance out of it remapped is extraordinary no matter which platform it is on. The S8 is no exception to that rule.
The Stage 1 ECU remap for 98RON improves the car’s performance significantly, gaining almost 0.6 seconds in 0-100km/h acceleration and a lot of power up to the rev limiter.

Remap modifications

In order to produce more power with reliability, the ECU’s torque model is tweaked. Further modifications are done to make sure there is proper fuel injection to cover the engine’s increased needs and ignition is also modified to make sure everything stays safe at all times.
In terms of boost, this is a comparison of stock vs Stage1 settings.


Performance results

  • 0-100 km/h: 3.4 sec (stock does it in over 4.0 sec)
  • 100-200 km/h: 8.1 sec (stock does it in over 10sec)
