Questions, answered.
Is remapping safe?
Yes. Every JWREMAPS file is developed and tested within OEM safety margins for injectors, turbo, clutch and gearbox — no shortcuts.
Will it improve my MPG?
Most drivers see a real-world improvement of 5–15% when driven the same way, thanks to better torque delivery lower down the rev range.
How long does the process take?
A typical Stage 1 remap takes 45–90 minutes. Diagnostics and pre-checks are included.
Can the map be returned to stock?
Yes — we always keep a copy of your original file and can restore it at any time, free of charge.
Does a remap affect my insurance?
You should inform your insurer of any modification. We provide a full remap certificate for your records.

Yes, we cover Newcastle upon Tyne and the wider North East — including Gateshead, Sunderland and Durham.
