What We Do

Our Services

From a simple fault code read to a full engine rebuild and performance remap — we handle every aspect of engine health and performance.

Engine Diagnostics

Full OBD-II and dealer-level diagnostics across all makes and models. We read fault codes, live data, and freeze frames to pinpoint the exact cause of any warning light or drivability issue.

ECU Remapping

Custom ECU remap tailored to your vehicle, fuel type, and driving style. Improve power, torque, throttle response, and fuel economy in a single session.

Stage 1 Upgrade

Software-only remap optimised for a standard vehicle. Typically delivers 20–40% more power and torque with no hardware modifications required.

Stage 2 Upgrade

Performance remap paired with hardware upgrades — intercooler, exhaust, induction kit. Significant power gains for drivers who want more from their build.

Engine Rebuild

Full strip-down, inspection, and rebuild of worn or damaged engines. New bearings, seals, gaskets, pistons, and rings fitted to manufacturer tolerances.

Turbo & Boost Diagnostics

Boost leak testing, turbo inspection, actuator testing, and wastegate diagnosis. We identify turbo faults before they become expensive failures.

DPF & EGR Solutions

DPF regeneration, cleaning, and fault diagnosis. EGR valve cleaning, testing, and replacement. Restore performance and economy on diesel vehicles.

Fault Code Clearing

Accurate fault code diagnosis and clearing after repairs are completed. We don't just clear codes — we fix the underlying fault first.
