Truck & Bus Remapping
At Drop The Box Performance, we specialise in Truck and Bus Tuning and ECU remapping for haulage companies, fleet operators, and bus services across Swansea, Carmarthenshire and South Wales.
Our goal is simple — to help you get more power, efficiency, and reliability from your trucks and buses so you can get more done, with less fuel and downtime.
With years of experience in commercial vehicle ECU remapping, we understand the demands of modern road transport.
That’s why our tuning services are tailored to your specific truck or bus, ensuring safe and effective results every time.
Truck and Bus ECU Remapping
Our Truck and Bus 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 trucks and buses work harder and more efficiently on the road.
Emissions Solutions
Many modern diesel trucks and buses suffer from emissions-related problems that can reduce performance, reliability, and increase running costs. We offer professional AdBlue deletion, DPF removal, and EGR blanking. These modifications can permanently resolve fault codes, significantly improve reliability, and lower operating and maintenance costs.
AdBlue Reduction & Torque Limitation
This solution can be applied to reduce your Adblue consumption whilst leaving the system fully operational, additionally we can also turn off the torque reduction or creep mode which activates when you have a Adblue system fault.
Diagnostic and Performance Support
As part of our commercial vehicle tuning service, we offer dealer-level diagnostics and performance checks. This ensures your truck or bus is running optimally before and after tuning. If we detect any faults, we can carry out programming, coding, or repairs to keep your vehicles 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.
