Why Tune a Bentley? Because 542–659 HP Is Just the Starting Point The Bentley Continental GT, Bentayga, and Flying Spur are among the most capable grand tourers on the planet — but they leave serious power on the table from the factory. Whether you own the 4.0-litre twin-turbo V8 or the legendary 6.0-litre twin-turbo W12, Bentley's engineers tune these engines conservatively for refinement, emissions compliance, and longevity across global markets. That conservatism is your opportunity. The V8 models share the EA825 (Continental GT / Flying Spur) and EA824 (Bentayga) architecture with Volkswagen Group stablemates like the Audi RS6 / RS7,...

The BMW M5 F90 is one of the most capable super sedans ever built — a 4.4-liter twin-turbo V8 producing 600 HP in standard form and 617 HP in Competition trim. But the factory exhaust system doesn't match the car's potential. It's heavy, over-muffled, and tuned to meet global noise regulations rather than deliver the sound a twin-turbo V8 deserves. If you're looking for the best exhaust upgrade for the F90 M5, this guide covers everything: titanium vs stainless steel, valvetronic vs straight pipe, weight savings, and which system is right for your driving style. Why Upgrade the F90 M5...

Why Downpipes Are the #1 Hardware Upgrade for the Aston Martin DBX & DBX707 If you own an Aston Martin DBX or DBX707 and want more power, downpipes should be at the top of your list. The Mercedes-AMG M177 4.0-litre twin-turbo V8 under the bonnet is a proven powerhouse — but the factory exhaust system leaves serious performance on the table. Restrictive OEM catalytic converters choke exhaust flow right where it matters most: at the turbo outlets. Upgrading your downpipes is the single most effective bolt-on hardware modification you can make, and when paired with a Stage 2 ECU tune,...

The Aston Martin DBX: A Remarkable Super SUV With Room for Improvement The Aston Martin DBX redefined what a luxury performance SUV could be. With its hand-built M177 twin-turbo V8, bespoke chassis, and unmistakable British design language, it carved out a unique space in the ultra-luxury SUV segment. But like any modern performance vehicle — especially one built around a complex forced-induction powertrain — the DBX has a handful of common issues that owners consistently report. The good news: many of these problems stem from conservative factory calibrations rather than hardware shortcomings. That means professional ECU tuning can address them...

Two Titans. One Question. Which Super SUV Makes More Power After Tuning? The Aston Martin DBX707 and the Lamborghini Urus Performante are the two most powerful production SUVs you can buy. Both pack twin-turbo V8 engines north of 650 horsepower. Both crack 190 mph. Both cost a quarter of a million dollars — or more. But the real question isn't which one wins on paper. It's which one responds better to ECU tuning — and which gives you more power per dollar once you move beyond stock. We've tuned both platforms extensively. Here's the full breakdown.
