Local Insight

Milford Haven's LNG terminal and refinery workers are regular economy remap customers, while Pembrokeshire's tourism sector drives demand for motorhome and towing tunes along the hilly coastal roads.

Our Services

Our Stage 1 calibrations deliver up to 35% more power for Haverfordwest drivers, with significantly improved throttle response and mid-range torque. Whether you're navigating busy town centre traffic or overtaking on the A40, A4076, A487, the improvement is immediately noticeable. The calibration is custom-developed for your exact engine variant and optimised for the mix of driving conditions across West Wales.

The frequent speed transitions between Haverfordwest's local roads and the A40, A4076, A487 put real demands on automatic and DSG gearboxes. Our calibrations deliver faster, more decisive shifts for motorway merging, reduced kickdown hesitation during overtakes, and smoother cruise-speed gear holding — making the daily commute across West Wales far less tiring.

Whether commuting from Haverfordwest along the A40, A4076, A487 or covering miles across West Wales, our economy calibrations deliver genuine fuel savings of 10-15%. We optimise fuel injection timing, boost pressure, and torque delivery for the speeds you actually drive at — not just peak-power figures you'll never use. The result is a vehicle that's more efficient without feeling slower.
