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 at no extra cost.
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.
Will it affect my insurance?
You should always inform your insurer of any modification. We provide a full remap certificate for your records.
