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.

Is Your Direct Injection Engine Losing Power? Many modern direct-injection engines slowly lose performance without their owners even realizing it. Over time, carbon deposits build up on the intake valves, restricting airflow and affecting combustion efficiency. The result? Reduced power, poor throttle response, rough idle, increased fuel consumption, and an engine that simply doesn't feel as sharp as it once did. That's exactly what brought this Audi SQ5 into our workshop. Th

When this 2012 Mercedes-Benz C63 AMG W204 6.3L V8 rolled into the workshop, the goal was clear — create a package that completely transforms the driving experience while keeping the raw AMG character alive. This wasn’t just a simple dyno tune. This build received a full combination of performance upgrades designed to improve power delivery, response, sound, and overall drivability. Upgrades Performed ✔ C63s headers ✔ High-flow bimodal catback exhaust system ✔ BlackBoost intak

When it comes to modern performance sedans, the Mercedes-AMG E63S sits at the top of the food chain. A twin-turbocharged 4.0L V8, all-wheel drive traction, and factory performance that already pushes supercar territory. But as we’ve seen time and time again — there’s always more left on the table. This particular 2020 E63S came into the workshop completely stock. No bolt-ons. No hardware changes. No CPC module upgrade. Just a proper dyno calibration. And the results speak f

Modern performance SUVs like the Audi SQ5 are impressive straight from the factory—but once mileage climbs, hidden issues can quietly steal power, efficiency, and drivability. This SQ5 arrived at Revhigh with just under 96,000km , and while it still drove well, the data told a different story. Direct-injection engines are notorious for carbon build-up, especially on the intake valves. Over time, this restriction reduces airflow, disrupts combustion efficiency, and limits how

Behind every great performance upgrade is quality fabrication — and this latest visit to our fabricator Jeff proves exactly that. Our newly updated Mercedes-Benz downpipe designs are officially in production, and the results speak for themselves. These aren’t off-the-shelf parts. Every detail has been refined to improve strength, flow, and long-term reliability for high-performance AMG applications. What’s New in the Updated Design? The latest revision focuses on durability
