MERCEDES SL63 R231 ECU REMAP

Custom Remap for the Mercedes-AMG SL63 (R231) at MSL Performance

Let’s be honest, you already own the quintessential performance roadster. The R231 SL63 is a brute in a velvet glove, a stunning blend of open-top luxury and the immense power of the 5.5-litre Bi-Turbo V8. It’s an iron fist in a silk driving glove. But have you ever been behind the wheel on a perfect day, roof down, and felt that while the power is immense, its delivery could be even more explosive? That there’s a sharper, more ferocious beast waiting to be unleashed? You’re right. There is.

Here at MSL Performance in Birmingham, we are experts in AMG’s legendary V8 engines. We don’t believe in generic, one-size-fits-all tunes. We’re about rolling up our sleeves and giving your SL63 the personal attention it deserves. We craft a completely custom map, specifically for your engine, to deliver a flawless uplift in performance that transforms the driving experience.

Find Your Perfect Level of Power

Every SL63 owner has a different vision. That’s why we’ve developed a clear tuning path, from a formidable enhancement to an all-out transformation.

Stage 1: The “Ultimate Grand Tourer” Tune

This is for the driver who wants to transform their SL63 from a fast roadster into a true supercar slayer, without changing a single piece of hardware. We meticulously recalibrate the engine and gearbox software to unleash a monstrous new level of performance. Throttle response becomes instantaneous, and the acceleration is transformed from merely fast into a relentless, horizon-pulling surge.

• The Result: Up to the 660 bhp mark and a colossal 150 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 Thunder

Ready to take your SL63 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 main restriction in the exhaust, allowing the twin turbos to spool faster and breathe more 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 makes every top-down drive an unforgettable event.

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