Mercedes C220d remap Nottingham
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 Nottingham C220d owners remap with us
Nottingham drivers spend a lot of time crawling the ring road and then opening up on the A52 or M1 — exactly the mix a well-written Stage 1 map improves. We see huge numbers of 2.0 TDI Golfs, 320ds and Transit Customs around NG postcodes, so the calibrations we write for them are refined over hundreds of local data-logs rather than pulled from a generic file database. Tradespeople in Bulwell and Clifton book us for van torque; commuters in Mapperley and Arnold want smoother mid-range for the hills; and enthusiasts in Wollaton and West Bridgford want Stage 2 files with proper before/after logging.
The Mercedes C220d is one of the vehicles we tune most around Nottingham, so the calibration is refined over many local data-logs on the A52, A60, A610, Nottingham Ring Road (A6514) and M1 junctions 24–26 — not a generic file. Every C220d gets a pre-map health check, VIN-specific write and a logged verification drive on your local roads.
