What you get

Professional stage 3 custom remap files built for the trade — for workshops, garages and mobile tuners in the UK and worldwide.

✓Fully bespoke. Every Stage 3 file is built to the individual build — no off-the-shelf maps.
✓Big-power ready. Suited to upgraded turbos, injectors, fuelling and supporting mods.
✓Work with our tuners. Share the full spec and goals; we calibrate to match.
✓Bench & boot friendly. Reads via bench/boot as well as OBD where required.

Is Stage 3 fully custom?

Yes — it's bespoke calibration for the specific modified build, not a database map.

What do you need from me?

A full spec of the build (turbo, injectors, fuelling, hardware) and the ECU read.

How long does it take?

Custom work takes longer than Stage 1/2 — we'll advise turnaround per job.
