Mercedes GLC63 AMG Remap
The Mercedes GLC63 AMG is a car we know personally - it's part of our own fleet. The M177 4.0-litre twin-turbo V8 in this performance SUV responds brilliantly to remapping: Stage 1 takes the GLC63 S from 510bhp to beyond 580bhp, transforming an already exceptional vehicle into something genuinely extraordinary. AutoCleanse provides GLC63 remapping in Devon from our Totnes workshop.

FAQ
Mercedes GLC63 AMG Remapping Questions
The GLC63 S 510 typically reaches 580–590bhp and 800Nm at Stage 1, a gain of around 70bhp and 100Nm. In a performance SUV context this is extraordinary - 0–60 drops to around 3.5 seconds and mid-range acceleration is genuinely shocking.
In our view, yes - the GLC63 is already a fast car, but Stage 1 adds a dimension that genuinely changes how it feels. The extra torque in particular transforms the mid-range, making overtaking and motorway driving feel effortless in a way the stock car doesn't quite match.
Stage 2 with downpipes, high-flow cats, and supporting modifications can push beyond 650bhp. At these levels the gearbox and drivetrain require assessment. For a road-used GLC63, Stage 1 delivers an exceptional result without complexity.
Remapping optimises the engine output, which feeds into all driving modes including AMG Dynamic Plus. The car feels more responsive in every mode, but the differences are most apparent in Sport+ and Manual.
Yes - contact us to book. We have hands-on experience with the GLC63 specifically. Turnaround is typically 1.5–2 hours including a thorough pre-remap health check.
