MERCEDES S63 W222 ECU REMAP

Custom Remap for the Mercedes-AMG S63 (W222 4.0 Bi-Turbo) at MSL Performance

Let's be honest, you already own the definitive high-performance luxury saloon. The facelift W222 S63, with its advanced 4.0-litre Bi-Turbo V8, represents the very pinnacle of automotive engineering—a seamless blend of ultimate comfort and breath taking power. But have you ever been behind the wheel, experiencing that incredible, silent surge of acceleration, and sensed that deep down, the engineers had to keep its final, most potent form in reserve? 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 latest and most sophisticated platforms. We don’t deal in generic, off-the-shelf tunes. For a flagship vehicle of this calibre, only a truly bespoke approach will suffice. We are dedicated to the art of custom remapping, connecting directly to your S63 to craft a flawless software solution that enhances its performance without ever 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 "Executive Supercar" Tune

This is for the driver who wants to elevate their S63 to a level of performance that can challenge dedicated supercars, all while retaining its factory hardware. We meticulously recalibrate the engine's complex 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 that feels both thrilling and utterly composed. It’s your S63, evolved.

• The Result: Up to the 690 bhp mark and an impressive 50 lb-ft of additional torque.
• What you need: Just your car! No extra parts are required.

Stage 2: For When You Demand Ultimate Authority

Ready to take your S63 to the absolute peak 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, along with a more enhanced exhaust note—a deep, purposeful V8 sound when you demand it, which remains perfectly civilised when cruising.

• The Result: Up to the 710 bhp mark.
• What you need: Downpipes are essential for this stage.
