Typical UK price ranges
As a rough guide, a Stage 1 remap on a normal road car usually falls between £250 and £400. A Stage 2 map — which assumes supporting hardware like an upgraded intercooler or exhaust — tends to run from around £350 upward. Economy or fuel-optimise maps sit in a similar bracket to Stage 1.
Those are ballpark figures, not a price list. The number that matters is the one for your exact vehicle, which is why we quote per car rather than publishing a flat rate that would be wrong for half of them.
What actually changes the price
Three things move the figure: how involved the read and write process is for your specific ECU (some need the unit opening up on the bench, which takes longer), whether you want a custom dyno-developed file versus a proven calibration, and whether any diagnostics or supporting work is needed first.
A car that's already healthy and uses a straightforward OBD flash is at the cheaper end. One that needs the ECU removed, or that has existing faults to resolve before tuning, costs more because there's more work in it.
Why the cheapest quote is a warning sign
If one quote is dramatically below the rest, ask what's being left out. A proper remap includes a diagnostic health check first, a full backup of your original file, and a calibration developed and safety-tested rather than a generic file copied across. Skipping those is how you save £50 and risk a far bigger bill later.
We back our remapping work through the Viezu master tuner network, with the original file always saved before we start, so the car can be returned to standard at any time.
Is a remap a one-off cost?
Yes — you pay once for the map. There's no subscription. If you later change the vehicle's hardware and want the map revised, that's a separate piece of work.
Does a cheaper remap mean a worse result?
Not always, but a price well below the market usually means a generic file, no diagnostics, or no backup — exactly where reliability problems start.
