Supporting specialist 4x4 tuning
Service the whole torque path.
Targeted drivetrain, software and emissions-system work for 4x4s that tow, work and go off road.
The systems we support
01 / Drivetrain systems
Where torque becomes traction.
Fluid condition, control software and mechanical health all shape how a tuned 4x4 performs under real load.
Automatic & manual
Transmission servicing
Correct-specification fluid, filters, inspection and post-service assessment.
Software & control
Transmission software
Updates, coding, adaptations and supported calibration for better gearbox behaviour.
Four-wheel-drive system
Transfer case servicing
Fluid servicing plus diagnosis of actuator, binding, noise and 4WD faults.
Front & rear axles
Differential servicing
Oil, contamination, leak and noise checks for hard-working final drives.
02 / Emissions & air path
Diagnose it. Repair it. Prove it.
We test the complete system before replacing parts, then verify the repair through live data and road testing.
Particulate filtration
DPF repairs & cleaning
Pressure, temperature and soot-load diagnosis with root-cause repair.
Exhaust gas recirculation
EGR diagnostics & repair
Command, airflow, valve and cooler testing before cleaning or repair.
AdBlue system
AdBlue & SCR repairs
Dosing, pressure, NOx sensor, heater, wiring and countdown diagnosis.
Documented use only
Competition calibration
Specialist ECU assessment for dedicated competition and non-road vehicles.
Road vehicles are supported through diagnosis, cleaning, repair, replacement and coding that restores manufacturer-fitted emissions systems.
03 / Assessment & protection
Start with evidence. Preserve the vehicle.
Establish a reliable baseline before tuning and protect the parts of a 4x4 that Welsh weather attacks first.
Not sure which system?
Send us the registration and symptoms.
Tell us what the vehicle is doing, how you use it and what has already been tried. We will point the enquiry in the right direction.
