Tuning & Remapping: what to know

Tell your insurer first

A remap is a modification. Insurers can refuse a claim if it wasn’t declared, so get a quote with the remap before you book it.

Ask for the numbers

A good tuner reads your car’s original map first, shows before-and-after figures (ideally on a rolling road) and keeps the original so you can go back to stock.

Stay road legal

Removing a diesel particulate filter (DPF) is illegal for road use and an MOT fail. Be wary of anyone offering DPF or EGR “deletes” for a road car.
