AUDI RS6/7 TUNING

We first started tuning the AUDI RS6 when a number our Supercar owning customers brought this popular daily driver in for further upgrades. We quickly purchased our own development C7 RS6 and continued to refine our tuning packages. Having our own car insures that not only is the performance transformed but the car keeps all its driveability, excellent fuel economy and enhances the cars incredible duality.


Our RS6/7 performance upgrades are applicable to both standard and performance edition cars. Please note that the power figures achieved remain the same for both editions.



Top Gear - 18th December 2015 - Litchfield RS6 Stage 3 with LM 90mm downpipes and Akrapovic Evolution exhaust:

"Mighty. Ridiculous. Entirely ballistic. Unutterably savage. Much quicker and noisier than standard. It devours fourth or fifth gear as easily as the standard one munches through third.

There’s no additional lag, you just apply throttle and the engine note deepens, the rear end squats and then you’re much further up the road, probably arriving at the next corner wishing you’d specified the carbon ceramic brakes."


Audi RS6 Dyno 2

Stage 1 - 675 PS (666bhp)



Our Stage 1 upgrade improves the already excellent standard RS6 or RS7 by remapping and calibrating the engine management system. This recalibration will release an extra 120 bhp on early C7 models and 75 bhp on the later Perfomance pack equipped cars. The upgrade will transform the way your Audi performs without pushing the limits of the standard components.


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
