Not every performance build is about chasing the highest dyno number. Sometimes, it's about creating a car that's more enjoyable to drive while maintaining reliability and delivering an incredible exhaust note.
That's exactly what Chris had in mind for his 2020 Mercedes-Benz C63 S W205.
After installing one of our RevHigh heat-shielded downpipe kits—with the help of a few mates over some drinks—he brought the car into RevHigh Performance Tuning for a custom Stage 2 dyno tune.
Customer Goals
Rather than pushing the limits of the factory hardware, Chris wanted a calibration that would:
Improve overall performance
Deliver a more aggressive exhaust note
Remain safe and reliable for everyday driving
This approach allowed us to tailor the tune specifically to the way the vehicle would be used, rather than simply aiming for the highest possible dyno figure.
Modifications
The vehicle was equipped with:
RevHigh heat-shielded downpipes
Custom dyno tune
CPC left untouched
Our heat-shielded downpipes improve exhaust flow while helping to manage under-bonnet temperatures, making them an ideal upgrade for the twin-turbo AMG V8.
Dyno Results
Baseline
320 kW at the wheels
Initial Calibration
401 kW at the wheels
Following the initial tune, the vehicle produced an impressive 401 kW at the wheels. While the available power was excellent, it exceeded the customer's performance goals.
Final Calibration
386 kW at the wheels
To match Chris's request for a more conservative setup, we refined the calibration and settled on 386 kW at the wheels—a level that delivered outstanding performance while maintaining the safe, reliable driving characteristics he was after.
Built Around the Customer
Every custom tune we perform is tailored to the owner's goals.
Some customers want every last kilowatt available, while others prioritise drivability, reliability, and long-term engine health. This C63 S is a perfect example of choosing the right balance rather than simply chasing the biggest dyno number.
The end result is a Stage 2 W205 C63 S with a fantastic exhaust note, noticeably improved performance, and a custom calibration designed specifically for the way the car is driven.
