Tractor and Agricultural Remapping


Our Tractor and Agri remapping service optimises your engine’s ECU software to improve performance without affecting reliability. We fine-tune torque, power delivery, and fuel economy to help your machinery work harder and more efficiently in the field.


Combine Harvester and Machinery Tuning


We also provide ECU tuning for combine harvesters, sprayers, loaders, and other farm machinery. Our technicians can adjust your machine’s performance to suit your working environment — whether that means more torque for heavy loads or better efficiency for long operational days.


Emissions Removal (Adblue, DPF & EGR)


A lot of diesel Vehicles suffer from emissions related problems, which can reduce Performance, Reliability & Production. We can remove one or all of these Systems which will permanently resolve any issues, make your Vehicle much more Reliable and reduce operating/maintenance costs.


Diagnostic and Performance Support


As part of our agricultural tuning service, we offer dealer-level diagnostics and performance checks. This ensures your equipment is running optimally before and after tuning. If we detect any faults, we can carry out programming, coding, or DPF cleaning to keep your machinery in peak condition.

After receiving a competitive quote off Darren I arrange for him to re map my Peugeot Boxer Motorhome. He arrived exactly on time and was very professional. I road tested after he had finished there was a noticeable improvement in power/torque. Will be recommending Drop the Box.
