Jason's Mercedes-Benz C63 AMG W204 came to Revhigh after a major engine refresh and some performance upgrades. Powered by the legendary M156 6.3L V8, the car had received reconditioned cylinder heads, updated head bolts, extractors and a set of performance camshafts. However, after having the car tuned elsewhere, Jason wasn't completely happy with how it was performing. Starting With a Dyno Test We put the C63 on the dyno to establish exactly where the car was at. The initial

The 2016 Audi RS7 C7 is already a serious performance machine, but the 4.0L twin-turbo V8 responds extremely well to improved exhaust flow. For this build, we fitted a set of Revhigh Catless Downpipes and put the car on the dyno to measure the results. Dyno Results Before:364.0 wheel kW814.1 wheel Nm After:445.5 wheel kW925.7 wheel Nm That's an impressive +81.5 wheel kW and +111.6 wheel Nm. In horsepower terms, the car gained approximately 109 wheel HP, which equates to rough

Modern direct injection engines are designed to deliver better fuel efficiency and improved performance, but they also come with a common issue that many vehicle owners don't realise—carbon build-up. Over time, carbon deposits accumulate on the intake valves and inside the intake ports, restricting airflow into the engine. This can reduce performance, increase fuel consumption, and cause a range of drivability problems. At Revhigh Tuning Solutions, we regularly see vehicles s

Modern vehicles are controlled by an Engine Control Unit (ECU)—the computer responsible for managing your engine's performance. From fuel delivery and ignition timing to throttle response and boost pressure, the ECU determines how your vehicle performs every time you drive. A professional ECU tune recalibrates these factory settings to better suit your vehicle and any performance modifications, delivering noticeable improvements in both performance and drivability. Here are s

Most people think naturally aspirated Holden V6 builds have already reached their limit — but Jayden’s 2012 LFX 3.6L VE Commodore proves there’s still serious performance hiding in these engines when the right combination is put together. This wasn’t just a simple bolt-on and tune package. The goal with this build was to create a stronger, sharper, and more responsive setup now, while also preparing the engine for future boost plans down the track. And the results speak for t

The Audi SQ5 has quickly become one of the most underrated performance SUVs on the market. Combining luxury, practicality, quattro all-wheel drive, and a twin-turbo diesel V6 platform with huge tuning potential, the SQ5 responds incredibly well to the right performance upgrades and calibration. At REVHIGH TUNING SOLUTIONS, we recently completed a full Stage 2 tuning package on this 2015 Audi SQ5 Biturbo — delivering stronger power, sharper throttle response, and noticeably im

Not every build starts with chasing power. Sometimes, it starts with fixing what’s wrong. This Holden Cruze came into the shop running extremely rich—sitting around lambda 0.7 , which is well outside where it should be. While that might sound “safe” to some, in reality it kills power, hurts efficiency, and can lead to long-term issues if left unchecked. So instead of jumping straight into adding more boost or throwing parts at it, we went back to basics. Getting the Foundati

Ryan’s VF SV6 Wagon already came equipped with a VCM OTR intake, performance exhaust, and a custom dyno tune, but we weren’t done yet. The goal? More power, sharper response, and an even more thrilling drive. Here’s what’s new under the hood: ✨ 3.7 Diff Upgrade — for harder, more aggressive launches and improved acceleration. ⚡ REVHIGH Racing Coil Packs + NGK Ruthenium Spark Plugs — delivering unmatched ignition precision, smoother throttle response, and rock-solid reliabilit
