MERCEDES S63 W222 ECU REMAP

Custom Remap for the Mercedes-AMG S63 (W222 5.5 Bi-Turbo) at MSL Performance

Let's be honest, you already own the ultimate expression of high-performance luxury. The W222 S63 is the benchmark, a sublime fusion of S-Class opulence and the immense power of the 5.5-litre Bi-Turbo V8. It is, by any standard, a masterpiece. But have you ever been behind the wheel, experiencing that effortless, continent-crossing surge, and sensed that deep down, the engineers had to restrain this engine's true, unbridled potential? A sharper, more commanding presence waiting to be unlocked? You're right. There is.

Here at MSL Performance in Birmingham, we are specialists in AMG's flagship V8 engines. We don’t deal in generic, off-the-shelf tunes. For a vehicle of this calibre, only a truly bespoke approach will do. We dedicate ourselves to the art of custom remapping, connecting directly to your S63 to craft a flawless software solution that enhances its performance without compromising its legendary refinement.

Find Your Perfect Level of Power

Every S63 owner has a different vision for their vehicle. That's why we've developed a clear tuning path, from a formidable enhancement to an all-out transformation.

Stage 1: The "First-Class Supercar" Tune

This is for the driver who wants to elevate their S63 to a level of performance that can humble genuine supercars, all while retaining its stock hardware. We meticulously recalibrate the engine's software to unlock a tremendous new level of power and torque. The throttle response becomes more immediate, and the car pulls with a newfound, relentless urgency. It’s the S63 you love, but with a shocking turn of speed that redefines effortless performance.

• The Result: Up to the 660 bhp mark and an incredible 100 lb-ft of additional torque.
• What you need: Just your car! No extra parts are required.

Stage 2: For When You Want to Unleash the Beast Within the Suit

Ready to take your S63 to the pinnacle of its performance and sound? Stage 2 is where we unchain the V8's true voice and fury. By installing high-flow downpipes, we remove the primary restriction in the exhaust system, allowing the twin turbos to breathe freely. This enables our custom tune to deliver a far more aggressive and sustained pull, accompanied by a glorious, deep and enhanced exhaust note that is purposeful when provoked, yet remains civilised when cruising.

• The Result: Up to the 680 bhp mark.
• What you need: Downpipes are essential for this stage.
