AUDI RS6/7 (C8) TUNING

The Audi C7 RS6 and RS7 models are one of the most popular cars we tune with huge performance ready to be unlocked. The latest C8 RS6 and RS7 are no different!

With its revised 4.0 Twin Turbo engine the C8 standard car now produces 600PS (591bhp) and 590lbft (800Nm) however with just our ECU calibration we can release over 100PS and 100lbft to transform the car.


Stage 1 - 700 PS (690 bhp)



Our Stage 1 upgrade dramatically improves the standard RS6 or RS7 by recalibrating the engine management system. The upgrade will transform the way your Audi performs without pushing the limits of the standard components. Driveability and engine response are also improved so the car is smoother as well as more powerful.


The Stage 1 Power upgrade includes:


  • Improved boost control
  • Revised ignition control, Variable Valve timing and Fuel maps
  • Reduced fuel consumption (especially on partial throttle conditions)
  • Increase in both power and torque across the whole rev range

Stage 2 - 730 PS (720 bhp)



The C8 RS models, like all new Direct Injection engines, are fitted with the new GPF/OPF particulate filter in the exhaust. Some version of this are more restrictive than others and in the C8 the standard exhaust is able to breath reasonably well through these. As such we offer a new Stage 2 option that supplies free flowing exhausts that connect up to the GPF/OPF to allow both an improvement in noise and performance without compromising the vehicles emissions status.

Our Stage 2 upgrade uses either a Milltek stainless steel exhaust or Akrapovic Evolution full Titanium system, which is 12 kg lighter than standard. This exhaust has its own carbon tail trims and uses the Audi software to control it's valves.


The Stage 2 upgrade includes:


  • ECU remap
  • Improved boost control
  • Revised ignition control, Variable Valve timing and Fuel maps
  • Reduced fuel consumption (especially on partial throttle conditions)
  • Increase in both power and torque across the whole rev range
  • Includes K&N replacement air filter
  • Optional Remus or Akrapovic exhaust systems available
  • Labour to fit (7hours) – No cutting required
