Bentley Continental GT & Bentayga ECU Tuning Guide — 4.0T V8 & 6.0T W12 Stage 1 & 2 Power, Mods & GCC Tips (2026)
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,...

McLaren 720S Downpipe Guide — Catless Race Downpipes vs Sport Cats | M840T 4.0T V8 | Power Gains, Sound & Installation
The McLaren 720S is one of the most devastatingly fast supercars ever built — and its M840T 4.0-liter twin-turbo V8 is the reason. Producing 710 HP from the factory, the 720S already embarrasses cars costing three times as much. But the factory catalytic converters sitting directly downstream of each turbocharger create a massive restriction where exhaust gas velocity is highest. Replacing them with aftermarket downpipes is the single most effective bolt-on modification you can make to unlock the M840T's full potential.This guide covers everything you need to know about upgrading the downpipes on your McLaren 720S: catless race downpipes versus...
Aston Martin DB12 Downpipe Guide — Catless & 200-Cell | M177 4.0T V8 | Power Gains, Sound & Installation (2026)
The Aston Martin DB12 is the world’s first super tourer — and under its sculpted bonnet sits the Mercedes-AMG M177 4.0-liter twin-turbo V8, producing 671 HP and 590 lb-ft from the factory. While Aston Martin calibrated the DB12 for grand touring refinement, the M177 platform has proven headroom well beyond factory output. Upgrading the factory downpipes is the most effective bolt-on modification to unlock that potential. This guide covers catless and 200-cell high-flow catted options, real-world power gains, exhaust sound changes, and why an ECU calibration is essential after installation.
