Mercedes C220d remap Derby
170 → 210 bhp · 400 → 460 Nm · £300 – £375 · on your driveway
The OM651 C220d is detuned from the same hardware as the C250d, so a Stage 1 safely closes that gap and more. The result is a far more relaxed motorway car — stronger in-gear acceleration and fewer downshifts from the 9-speed.

Why Derby C220d owners remap with us
Derby is an engineering city, and Derby drivers ask better questions than most — about torque curves, EGT limits and what the data-log actually shows. We like that. Daily commuters on the A38 and A50 want a Stage 1 that fills in the mid-range and settles the DSG or 8-speed auto; tradespeople in Sinfin, Alvaston and Spondon want their Transporter or Vivaro to pull properly when loaded; and performance owners in Allestree, Mickleover and Darley Abbey want Stage 2 calibrations with hardware-matched boost and logged proof of the result.
The Mercedes C220d is one of the vehicles we tune most around Derby, so the calibration is refined over many local data-logs on the A38, A50, A52, A6 and M1 junction 25 — not a generic file. Every C220d gets a pre-map health check, VIN-specific write and a logged verification drive on your local roads.
