MERCEDES C43 W205 / GLC43 X253 / GLE43 W166 PFL ECU REMAP

Custom Remap for the Mercedes-AMG C43 (Pre-Facelift) at MSL Performance

Let's be honest, you already own a fantastic car. The C43 is the sweet spot in the AMG lineup, delivering thrilling BiTurbo V6 performance and all-weather capability in a stylish package. But have you ever planted your foot and felt that, deep down, this potent V6 engine has more to give? A sharper response, a more aggressive pull, a whole new level of excitement waiting to be unleashed? You're right. There is.

And here at MSL Performance in Birmingham, we know exactly how to unlock it. We're not about generic, one-size-fits-all tunes that get emailed around. We’re about rolling up our sleeves and giving your C43 the personal attention it deserves. We craft a completely custom map, specifically for your engine, your fuel, and the parts you have fitted. It's like a bespoke suit for your engine – a perfect fit that delivers incredible performance, safely.

Find Your Perfect Level of Power

Every driver is different. That's why we've developed a clear tuning path for your C43, from a significant enhancement to an all-out transformation.

Stage 1: The "True AMG Experience" Tune

This is for you if you love your car's balance but want to elevate it to the next level of performance. On standard hardware, we meticulously recalibrate the engine's brain to unlock a whole new level of energy. The throttle response becomes instantaneous, and the car pulls with a newfound urgency through the entire rev range, pinning you to your seat. It’s the car you already love, but with the authentic, aggressive AMG character it always deserved.

• The Result: Up to 430-440 bhp and an impressive 50-60 lb-ft of additional torque.
• What you need: Just your car! No extra parts are required.

Stage 2: For When You Want to Make a Statement

Ready to close the gap on bigger V8s? Stage 2 is where things get seriously fun. By freeing up the exhaust flow with high-flow downpipes, we can get more aggressive with our custom tune. This allows the twin turbos to spool faster and breathe more efficiently, delivering a harder, more sustained pull right to the redline. The power delivery is more intense, and the exhaust note becomes a glorious, unapologetic roar that will make you smile every single time.

• The Result: Up to a formidable 450-460 bhp.
• What you need: High-flow downpipes (decat or sports cat) are required to let those turbos breathe.
