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.
"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."
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:
Our Stage 2 upgrade features the Milltek performance cat-back exhaust and replaces the more restrictive standard exhaust system. The Milltek system retains the OE tail trims to maintain the factory look and is also available with a resonating box.
There is also the option to have the Remus stainless steel and Akrapovic Evolution full Titanium system, which is 8 kg lighter than standard. This exhaust has it's own carbon tail trims and uses the Audi software to control it's valves.
The Stage 2 Power upgrade includes:

Our Stage 3 upgrade starts with the full Milltek performance exhaust (including downpipes). This full system replaces the restrictive OE cats with straight through downpipes to reduce back-pressure and increase the total open area. There are also Remus and Akrapovic options. The Akrapovic system can be combined with our unique UK made 90mm Litchfield Downpipes to release the full power. All the exhausts use valve technology with the Audi software for different sound options.
Combined with and free flowing intake filter and our unique ECU recalibration this upgrade lifts performance upto an incredible 750bhp.
