Ford Fiesta ST remap Derby
200 → 230 bhp · 290 → 340 Nm · £300 – £350 · on your driveway
The Mk8 Fiesta ST is a Stage 1 favourite in Nottingham and Derby — the 1.5 EcoBoost has plenty of headroom and the car gains a much stronger mid-range without losing the crisp throttle Ford built in. Stage 2 with an intake and intercooler is a popular next step.

Why Derby Fiesta ST 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 Ford Fiesta ST 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 Fiesta ST gets a pre-map health check, VIN-specific write and a logged verification drive on your local roads.
