Mercedes-Benz C-Class,
woken right up.
The C-Class turns up in a sharp suit but leaves the factory politely holding back, whether it's diesel torque or petrol pace you're after. We arrive at your door with dealer-level tools, let it finally act its price tag, and store your original map so it's fully reversible.
Typical Stage 1–2 gains — up to
bhp
Nm torque
Estimated peak gain across C-Class engines. Your car's figures depend on spec, year, fuel & condition — we quote honest numbers, never fantasy dyno bragging.
So, what's in it for your C-Class?
That refined, unhurried C-Class demeanour is partly Mercedes engineering and partly Mercedes holding back. One engine map has to work across every market, fuel grade and emissions test going, so your car left Stuttgart detuned with headroom left spare. Very polite. Very cautious. Very fixable.
On the C200d, C220d and C250d diesels that headroom turns into a proper slug of extra mid-range torque — the effortless, wafting shove a C-Class was born to have — and often better MPG if you drive like a grown-up. The C200 and C300 petrols wake up with genuine power and cleaner pace, the eager side Mercedes tends to keep on a leash. W204 or W205, it responds beautifully.
We come to you — home or work — with genuine dealer-level tools running on a stable power supply, because an interrupted flash on a tired battery is nobody's idea of German precision. Your original file is backed up before we touch a thing, so it's fully reversible. DPF, EGR and AdBlue are left intact and road-legal. Results vary by year, spec, fuel and condition, so we quote an honest estimate for your C-Class, not a number borrowed from a dyno you'll never see.
The numbers (the fun part)
Standard vs remapped, per engine. Bars are scaled to peak bhp — the red is what you've been missing.
C200d (2.1 CDI, W204/W205)
C220d (2.1/2.0 CDI)
C250d (2.1 CDI)
C200 petrol (1.5/2.0 turbo)
C300 petrol (2.0 turbo)
Stage 1: ≈ 280–300 bhp / ≈ 430–460 Nm · Stage 2 shown (needs supporting hardware)
Typical estimates for a healthy vehicle. Stage 2 needs supporting hardware (intake/exhaust/intercooler) — we'll only suggest it if your car's up for it.

What's in the box
The small print (yeah, yeah): always tell your insurer about a remap — it's a mod, and "forgetting" can sink a claim. If your C-Class is still under manufacturer warranty, a remap can affect powertrain cover, so weigh it up first. We keep your original file backed up either way.
Questions you're about to ask
Do you really remap the C-Class at my home?
Yes — we're a mobile service. We come to your home or workplace anywhere in our coverage area with genuine dealer-level tools and a stable power supply, and the whole job is done on your driveway. No garage visit, no waiting room.
Will it damage my engine or DPF?
No. Our performance and economy maps are designed to work within the mechanical limits of your engine and keep the DPF, EGR and all emissions kit fully intact and road-legal. We don't do delete maps on cars used on the road.
Can the remap be undone, and do I tell my insurer?
We read and back up your original factory file before we write anything, so your C-Class can be returned to standard at any time. And yes — a remap is a modification, so declare it to your insurer to keep your policy valid.
