MERCEDES A45 W176 / CLA45 C117 / GLA45 X156 ECU REMAP

Custom Remap for the Mercedes-AMG A45, GLA45 & CLA45 at MSL Performance Let's be honest, you already own a fantastic car. The A45 and its siblings are pocket rockets from the factory, an absolute blast to drive. But have you ever planted your foot and felt that, deep down, there's just... more? A little more kick, a bit more urgency, a whole lot more excitement waiting to be unleashed? You're right. There is. And here at MSL Performance in Birmingham, we know exactly how to find 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 car 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 few paths you can take on your tuning journey, from a subtle enhancement to an all-out transformation.

Stage 1: The "This is How it Should've Been!" Tune

This is for you if you love your car as it is but just want to awaken its true spirit. On standard hardware, we meticulously recalibrate the engine's brain to unlock a whole new level of energy. The slight hesitation from a standstill? Gone. The mid-range pull? Now it's a forceful shove that pins you to your seat. It’s the car you already love, but with its personality turned up to eleven.

• The Result: Up to 410 bhp and a massive 100 lb-ft of extra torque.
• What you need: Just your car! No extra parts are required.

Stage 2: For When You Want to Make a Statement

Ready to add a bit more drama? Stage 2 is where things get seriously fun. By freeing up the exhaust with a decat downpipe, we can get more aggressive with our custom tune. The car pulls harder for longer, the power delivery is more intense, and the sound becomes a glorious, unapologetic roar that will make you smile every single time.

• The Result: Up to a mighty 430 bhp.
• What you need: A decat downpipe to let that engine breathe.

Stage 3: Welcome to Supercar Territory

This is it. The ultimate upgrade. This isn't just a remap; it's a complete transformation that turns your AMG into a genuine giant-killer. We work our magic to get a hybrid turbo, a downpipe, and all the supporting mods talking to each other in perfect, powerful harmony. The acceleration is savage, relentless, and will have you chasing down cars that cost three times as much.

• The Result: An incredible 475 bhp.
• What you need: A hybrid turbo upgrade and a decat downpipe are the essentials.
