What Our Customers Say
"Had my D300 Discovery l462 remapped to D350 spec. The difference is night and day. Overtaking is effortless and the gearbox is so much sharper. JLR Engineering handled everything remotely in under two hours."
Michael T. β Discovery l462 5 D300

Yes. Most modern JLR vehicles can be tuned remotely via secure connection. For older models, we can post you a programming interface or arrange a mobile visit.

We can revert to stock before sale at no charge. Alternatively, you can sell the tune as a transferable feature to the new owner for a small transfer fee.
