C63 tuning


(C/S/W205: 2015- )

Following on from our successful Mercedes C63 AMG (W204) tuning, we were excited to start tuning the new turbo-charged V8 in the C63 W205. As the new engine has forced-induction we are able to obtain significant power gains with our ECU remaps and performance exhaust systems.

Stage 1 - ECU Remap

We are delighted to introduce our AMG 4.0T remaps that can now be programed through the On Board Diagnostic (OBD) port so more time can be spent on honing the calibration. It also means we can revert the car back to standard at any time by uploading the original file. Our Stage 1 upgrade for the C63 & C63s turbo charged engines offers a massive increase in power and torque through its carefully re-calibrated ECU. Engine power increases to around 570 bhp (+100 bhp on the standard C63) and torque increases to around 580 lbft (+100 lbft/136 Nm) which transforms the way the car drives. The vehicle Speed Limiter is also removed as part of our Stage 1 calibration. We take great care in insuring we are able to provide the very best calibration rather than using a generic off the shelf file with hours of dyno time going into refining what we are able to offer our customers.

Stage 1 - ECU Remap - 2019+ Model Year AMG 4.0T

Some of the later 2019+ AMG 4.0T still require us to plug into the ECU which takes around 6 hours to complete. The tune is the same, but the process takes us much longer.

Stage 2 - ECU Remap with Akrapovic Evolution exhaust

Stage 2 for the C63 AMG is based around the excellent Akrapovic Evolution Line (Titanium) exhaust with a remap to suit. The exhaust is made from specially developed ultra-lightweight titanium alloys and finished with hand-crafted matte carbon fibre tailpipes. It saves a huge 13 kg over the original exhaust and is a direct replacement for both standard and performance versions. If the car is not fitted with the Mercedes performance exhaust then an extra Valve Actuator Kit is mandatory. There is also an Akrapovic sound kit available for the C63 (W205), however this is not needed if the car is already fitted with an exhaust valve button.

The Akrapovic Evolution Line (Titanium) is available as a separate upgrade on it's own, is ECE type approved and will give the car a further 8 bhp and 20 lbft. With the Litchfield stage 2 remap the car will gain an extra 120 bhp and 140 lbft. We would expect the exhaust to take 4 hours to fit.
