Started by Gavin Warner from a Merthyr Tydfil workshop — Future Remapping grew out of frustration with cheap, copy-paste remaps damaging engines, voiding warranties and ruining MPG. We do it the way it should be done. ### Who we help Daily commuters chasing real-world MPG, tradespeople running vans down to Cardiff and Bristol every day, farmers and contractors getting more out of tractors and pickups, and enthusiasts who want a properly calibrated Stage 1 or Stage 2 file — not a generic download. ### What we specialise in ECU remapping (Stage 1 and Stage 2), full diagnostic-led tuning, DPF / EGR / AdBlue work, engine management light removal, and dedicated truck, tractor and plant calibration. One discipline, done properly — not a general garage that 'also does remaps'. ### Experience depth 5+ years writing files on the South Wales vehicle mix — VAG diesels, Ford and Vauxhall vans, BMW estates, Hilux and Ranger pickups, Defenders, John Deere and Massey tractors, JCB plant. Every file we load has been tested on that exact engine/gearbox combination, not just downloaded and hoped. ### Service area Mobile across all of South Wales — Merthyr Tydfil, Cardiff, Swansea, Newport, Bridgend, Caerphilly, Cwmbran, Port Talbot, Chepstow, and every postcode between. We come to your driveway, your yard, your workplace or your farm. Mission & standards ## The standards we hold every job to. We treat every car like it's about to do another 100,000 miles — because most of them will. That shapes everything: the diagnostic we run first, the file we load, the road-test we do after, and the records we keep.

We document ECU serial, mileage and file checksum on every job. ### Service philosophy Diagnostic first, calibration second. If your engine has an underlying mechanical or sensor fault, a remap won't fix it — and we'll tell you before any file change. We won't tune a vehicle we don't believe in. ### Reversibility Stock file stored safely before any change. We can return your vehicle to its original file at any time, free of charge — provided you bring the vehicle to us. ### Honest pricing Free, no-obligation quotes by registration, typically within 24 hours. Price is confirmed once we know the exact vehicle and location. No callout fee, ever. Training ## Qualifications & Accreditation Calibration is a skilled trade. Every file we write is backed by formal, IMI-accredited tuner training — not a weekend course.
