MERCEDES E63 / E63S W212 ECU REMAP

Custom Remap for the Mercedes-AMG E63 & E63S (W212 5.5 Bi-Turbo) at MSL Performance

Let's be honest, you already own a brute in a suit. The W212 E63, powered by the legendary 5.5-litre Bi-Turbo V8, is the definitive executive missile – a luxurious saloon with a sledgehammer hidden under the bonnet. But have you ever planted your foot, felt that immense wave of torque, and had the feeling that deep down, this engine is capable of so much more? That AMG built it with a whole other level of ferocity just waiting to be unleashed? You're right. There is.

Here at MSL Performance in Birmingham, we are experts in AMG's powerhouse V8 engines. We don’t deal in generic, off-the-shelf tunes. We are dedicated to the art of custom remapping, rolling up our sleeves and giving your E63 the personal attention it deserves. We craft a completely bespoke map for your specific engine, unlocking a level of performance that will redefine what you thought your car was capable of, all while maintaining safety and reliability.

Find Your Perfect Level of Power

Every E63 owner has a different goal. That's why we've created a clear tuning path to help you achieve the exact level of performance you crave, from a mind-blowing uplift to an all-out assault on the senses.

Stage 1: The "Autobahn Dominator" Tune

This is for the driver who wants to transform their E63 into a genuine 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 becomes a relentless, horizon-pulling surge. The car is transformed from a fast saloon into an all-weather weapon with shocking straight-line speed.

• 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 E63 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 most significant restriction in the exhaust system, allowing the twin turbos to spool faster and breathe more efficiently. This enables us to get far more aggressive with our custom tune, resulting in a phenomenal increase in power and a much more enhanced exhaust note. The car pulls with violent intensity, accompanied by a glorious, thunderous V8 roar that will make every drive an event.

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