Ford Fiesta ST remap Leicester
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 Leicester Fiesta ST owners remap with us
Leicester is a big, varied city and the work reflects it. M1 and M69 commuters in 2.0 TDI Golfs, 320ds and A4s want a Stage 1 that fills the mid-range and settles the auto box for the daily grind; enthusiasts around Clarendon Park, Oadby and Evington book Stage 2 GTIs, Fiesta STs and Focus STs with hardware-matched maps and logged before/after figures; and trades in Braunstone, Wigston and Thurmaston run Transporters and Transit Customs that need torque when loaded. Every Leicester job is fully mobile, VIN-specific and verified on local roads — not a generic file.
The Ford Fiesta ST is one of the vehicles we tune most around Leicester, so the calibration is refined over many local data-logs on the M1 junctions 21–22, the M69, A6, A46 Leicester ring road and A47 — 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.
