Professional. Mobile. Trusted.
A genuine custom Stage 1 ECU remap from a reputable mobile tuner in 2026 sits between £249 and £549 depending on platform — and that's the only price you should pay. Cheap £150 'generic file' jobs are off-the-shelf maps that don't account for fuel quality, intake mods, mileage or DPF state, and a £700 dealer-level price is markup. StageMyCar publishes its 2026 pricing publicly: £249-£299 small petrol / diesel (Fiesta, Polo, Corsa, 1.0-1.4 TSI/TDI), £299-£349 mainstream (Golf GTI, A3, 320d, Focus ST), £349-£399 premium / performance (340i, M140i, S3, RS3, 535d, Macan), £399-£549 ultra-premium (M-series, RS, AMG, Range Rover SVR, Porsche 911). Every job is custom-written, logged before and after, and backed by a 12-month software warranty.

Frequently Asked Questions
How much does a Stage 1 remap cost in 2026?+
£249-£399 for most petrol / diesel cars. Premium platforms (Porsche, Range Rover, RS / AMG / M) £399-£549. Always fixed price, quoted on registration.
What's included in the price?+
Full custom Stage 1 file, before/after dyno-style logging, 12-month software warranty, free revert-to-stock, and a written report.
Is it cheaper than a chip box or piggyback?+
Yes long-term. A proper ECU remap is one-off, undetectable on revert, and gives better, safer gains than a piggyback that sells for £300-£600 and stays visible to dealers.
Will it affect my warranty?+
Aftermarket tunes are not legally warranty-voiding for unrelated components in the UK. We can revert to stock free of charge before any dealer visit.
Do I need to insure it?+
Yes — declare it as a modification. Most mainstream insurers add £30-£90/year, some add nothing. We provide a written spec for your broker.
Finance / Payment Assist?+
Yes — 3 or 4 monthly instalments, 0% APR on selected jobs over £250. Subject to status.
